Will Taylor Swift play the six tracks she's never performed during Eras Tour surprise set?

Will Taylor Swift play every song from her studio albums before the Eras Tour wraps up on Sunday in Vancouver, Canada? Will she bring out special guests? Will she sing "You're On Your Own, Kid" one more time?

"Welcome to the acoustic set," Swift says, beaming, to a sold-out crowd every night of the tour.

Livestreamers have countdown clocks and ardent supporters have alerts that notify them when the acoustic set is beginning. Each one is different, and most lead to a news story (I've covered 89 of them). Swift performs one song or mashup on the guitar and a song or mashup on the piano.

Every once in awhile, she announces a rerecorded album like "Speak Now (Taylor's Version)" in Nashville or "1989 (Taylor's Version)" in Inglewood, California. Sometimes she brings out a surprise guest like Sabrina Carpenter in New Orleans or Gracie Abrams in Toronto. Some of the songs form a message to the crowd, like during her final American concert in Indianapolis when she blended "Cornelia Street" and "The Bolter" to create the line, "I don’t want to lose you / I hope it never ends / but she was leaving / and it felt like freedom."

From Swift's 11 studio albums, there are six tracks she hasn't played yet: "That’s When" and "Bye Bye Baby" from "Fearless (Taylor's Version)"; "Girl At Home," "Ronan" and "Forever Winter" from "Red (Taylor's Version)"; and "Soon You’ll Get Better" from "Lover."

With an average of four songs every night and three Canadian shows left, the Eras Tour ringleader may not play every song before the confetti falls on the Sunday crowd in BC Place. Especially since one of them she said she'd never perform live.

'Ronan'

In 2021, on the rerecorded version of "Red," Swift added Track 21: "Ronan." The song captures a form of heartbreak no parent should have to face: the loss of a child.

"I never expected 'Ronan' to be on an album of hers," says Maya Thompson, "so getting that phone call was just, I'm still in a pinch-me moment from that. I feel like I'll be in a pinch-me moment for the rest of my life over that."

Thompson chronicled losing her 3-year-old, blue-eyed son, Ronan, to neuroblastoma in May 2011. Swift found the grieving mother's blog and penned a song, taking direct quotes from Thompson's perspective for the 4:26 track. During a 2012 Stand Up to Cancer telethon, Swift performed the heartbreaking song.

"I'm so honored that she chose to put it on such a special album," Thompson says, "and the fact that that song means so much to her and she's just continuously been honoring his memory and who he was and everything he represents. To a bereaved mom, that just means everything to me."

Thompson will be in Vancouver for one of the final shows and anticipates Swift would want her to be in the crowd if "Ronan" was chosen as a surprise song.

"I don’t know. I leave it up to her," she says. "I think about it in the perspective that I worry about Taylor. … How would she be? Would she be OK with this? Is this something she would be able to get through? With that being said, I would love it."

'Soon You'll Get Better'

In March 2019, five months before Swift's seventh album "Lover" was released, she wrote 30 lessons she learned in Elle magazine. No. 24 read in part, "Both of my parents have had cancer, and my mom is now fighting her battle with it again. It’s taught me that there are real problems and then there’s everything else. My mom’s cancer is a real problem."

During a YouTube live with fans, Swift talked about Track 12, "Soon You'll Get Better," a melancholic melody featuring The Chicks about being in-and-out of hospitals as Swift's mom, Andrea, battled cancer.

"We as a family decided to put this on the album," she said on the livestream, "and it's something I'm so proud of, but it's just really hard. I can't sing it. It's hard to just emotionally deal with that song. You'll understand what I mean in a couple hours."

The singer reiterated the gravity of the song during a SiriusXM Town Hall Q&A session with fans.

"That's a song I don't know if I'll ever play it live," she said. "It's just really difficult for me. It was hard to write. It's hard to sing. It's hard to listen to for me, but sometimes music is like that. Sometime's it's not just about stuff that was pleasant to feel."

In 2020, Swift performed the heart-wrenching track for the live broadcast of Global Citizen's "One World: Together at Home" benefit concert supporting health care workers and the World Health Organization.

'Forever Winter' and 'Girl At Home'

The two tracks left from "Red (Taylor's Version)" have two very different themes. "Forever Winter" chronicles a friend going through an incredibly dark and depressive time and not knowing how to help as the situation becomes grave. Swift sings, "If I was standing there in your apartment / I'd take that bomb in your head and disarm it / I'd say I love you even at your darkest / And please don't go."

In "Girl At Home," Swift uses dance club synths to tell the story of being hit on by a man who has a girlfriend waiting at home. Swift told Yahoo! News in October 2014, "And there's a song called 'Girl at Home,' which was about a guy who had a girlfriend, and I just felt like it was disgusting that he was flirting with other girls."

'That's When' and 'Bye Bye Baby'

The two "Fearless (Taylor's Version)" vault tracks she hasn't played are "That's When" and "Bye Bye Baby." "That's When" is a duet with country singer Keith Urban. He told Ellen DeGeneres about getting a message from Swift while he was in a mall food court.

"I'm at the shopping mall doing my Christmas shopping and I get a text from Taylor saying, 'I've got these couple of songs I'd like you to sing on, do you want to hear them?' and I said, 'Sure.'" She sent him "That's When" and "We Were Happy."

"Bye Bye Baby" would be a great final line for the last acoustic set of the Eras Tour, although the song might not make the best parting message as it's about leaving unrequited love and hope for the future in a cloud of dust.

Other songs

"I don't know if any of the tracks she hasn't done are likely to be played," says Kayla Wong, a Swiftie who keeps track of all data on the superstar. Her Instagram account, @headfirstfearless, follows the statistics behind the most common acoustic songs. "The most likely scenario is probably coming back with big fan favorites."

Wong says the top five songs Swift has performed during the acoustic set are:

• 11 times: "You're On You're Own, Kid"

• Nine times: "Maroon"

• Seven times: "Out of the Woods

• Six times: "Clean"

• Six times: "Death By A Thousand Cuts"

"I wouldn't be surprised if she does 'You're On Your Own, Kid' one more time on the last night," Wong says. "I also think 'Long Live' will be in the mix."

And you thought you were a fan: See the Taylor Swift-inspired Christmas House in Naperville, Illinois.

If you're looking at odds, Wong points out that "Speak Now (Taylor's Version)" and "Red (Taylor's Version)" have the most surprise songs performed at least four times. Other factors to consider: Swift could invite special guests, make an announcement or do an unexpected song like performing "This Is What You Came For" on June 14 in Liverpool or "Crazier" on June 8 in Edinburgh.

In her official Eras Tour book, the singer claimed, "It takes a lot of rehearsing to get the mashups just right, but when the crowd screams like crazy when I transition into a new song, it's beyond worth the prep time involved."
