Julianne Hough and Aaron Tveit are having a blast taking on the iconic roles of Danny and Sandy in Fox's Grease: Live. But while the stars are huge fans of all the Greasesongs, there are a few in particular that they're especially excited for the audience to see.

"There's a section in our show where we pull a song from the Broadway version called 'Magic Changes,'" Tveit tells TVGuide.com. "It's the part where Danny's trying out for all the sports teams... That's probably my favorite section of the show."

"You should watch the guys do 'Greased Lightning.' It's pretty spectacular, pretty amazing," Hough teases.

Grease: Live airs Sunday at 7/6c on Fox.
