John Travolta is in awe of the stars in Grease: Live.
The 61-year-old actor famously played Danny Zuko in 1978 movie Grease. On Sunday night, a cast including Vanessa Hudgens, Julianne Hough, Carly Rae Jepsen and Aaron Tveit will be performing the musical live on the Fox television network - a prospect that terrifies veteran performer John to his core.

He said of Grease: Live: "I don't know if I could do that! I did it on Broadway but I don't know if I could now do what those kids are about to do. I take my hat off to them for it."
