Here's the info we have at the DIS!
Goofys Country Dancin Jamboree, a unique interactive character experience, debuted at The Diamond Horseshoe at the Magic Kingdom Park on July 1.
Just returning from the big city, Goofy is eager to teach Magic Kingdom Park guests the current line dances he learned and has invited some of his closest friends to join in. With the help of a live country singer named Sarah Jo, friends Chip n Dale and others, Goofy teaches guests the "Electric Slide," "Boot Scootin Boogie," "Cotton Eyed Joe" and Goofys own dance creation, "The Goofy Two-Step."
The 18-minute dance party, which doesn't include food or beverage services, is designed for guests of all ages and allows the characters to interact with guests on the dance floor. Seating is not available on the first floor, however guests will be encouraged to take pictures of their children and other family members from the second-floor balcony.
