Watch Kelly Clarkson perform 'Banana Boat (Day-O)' as Beetlejuice for Halloween: 'It's showtime!'

The cover paid homage to the 1988 film, with Clarkson's house band Y'all dancing in unison as if similarly possessed by mischievous ghosts.

Well, this Kellyoke cover has just made our millennium. 

Kelly Clarkson transformed into the ghost with the most, Beetlejuice, on Thursday for an extra ap-peel-ling performance of Harry Belafonte’s “Banana Boat (Day-O).” The host — dressed in the character's signature striped suit with waxy green hair and slime-covered teeth — opened the Halloween episode of her talk show resting in a grave before slowly rising up from the ground as she sang along to the 1956 song.

And, as it turns out, Clarkson wasn’t the only one committed to the bit. Her house band, Y’all, also dressed up as multiple characters from both 1988's Beetlejuice and this year's sequel, Beetlejuice Beetlejuice, including Adam Maitland, ghost detective Wolf Jackson, Bob, a deceased football player, and Lydia Deetz.

The group even paid homage to the original film's “Banana Boat (Day-O)” scene during their performance, with the band similarly possessed by a collection of mischievous spirits that made them all jerkily dance in unison to the song.

Clarkson also tried her best to evoke Michael Keaton’s husky Beetlejuice tone as she spoke, turning to bandmate Jessi Collins, who was dressed as Lydia, and asking, "Hey, you come here often?”

After the performance, Clarkson welcomed viewers to the show and confirmed its Beetlejuice theme extended to much more than just their opening number. “It’s showtime,” she began. “Happy Halloween. Welcome to The Kelly Clarkson Show. And today, if you couldn’t guess, we’re all about Beetlejuice. You’re welcome.”

Clarkson added that the show had fully converted its entire stage into the model city from the Maitlands' attic, complete with a sprawling graveyard, a sandworm, the hallway to the afterlife offices, Bob's office, and even had a copy of the "Handbook for the Recently Deceased" at the ready.

Clarkson is one of, fittingly, three talk show hosts who decided to dress up as the bio-exorcist on television for Halloween this year. Al Roker and Mark Consuelos similarly sported the character’s striped suit on Today and Live With Kelly and Mark, respectively.

Speaking to Entertainment Weekly earlier this summer, Catherine O'Hara detailed the making of the supernatural scene in the beloved Tim Burton classic. "There was a man, a crew member, under each of our place settings under the table with a shrimp glove on that sat on the shrimp cocktail dish until the moment when they're supposed to attack our faces," she explained. "They'd get a cue, and being human beings, there'd be a little delay or there'd be jumping the cue. So you never quite knew when it was going to happen, even though it was so fun. It made it really scary.

She continued, "I think we shot it for a couple of days, all day long. And we all added moves. We had a choreographer, but we all got to add our stupid moves. When you're shooting it, you could sort of tell, but you can't tell.... The idea was great and the song is so great, but then just the way it was put together, I had no idea it was going to be that fun and powerful and memorable."
