It’s the most wonderful time of the year! At least according to Julianne Hough and her brother Derek Hough.

The Dancing with the Stars siblings will perform the holiday classic “It’s the Most Wonderful Time of the Year” as the opening number on The Wonderful World of Disney: Magical Holiday Celebration.

The special won’t air until Thanksgiving, but PEOPLE has an exclusive First Look at the performance — complete with an appearance by Mickey Mouse!

The Hough siblings host the event and are joined by Descendants 2 star Sofia Carson to kick off the Christmas season.

The special was filmed at both Disneyland in Anaheim, Calif., and Walt Disney World in Orlando. It will also feature performances by Mariah Carey, Kelly Clarkson, Trisha Yearwood and husband Garth Brooks, Boyz II Men, Alessia Cara, JoJo, Flo Rida and OneRepublic.

The Wonderful World of Disney: Magical Holiday Celebration two-hour special airs Thursday at 8 p.m. ET on ABC.
