John Travolta's Danny Zuko reemerged at the Hollywood Bowl, 47 years after the star portrayed the Rydell High T-Bird in 'Grease' the movie.

"Grease," based on the hit 1972 Broadway musical of the same name, follows Danny, a local bad boy, and Sandy (Olivia Newton-John), a wholesome high school transfer student from Australia, as they reunite at Rydell High School after meeting at the beach over the summer.

Fans at the 'Grease' Sing-A-Long screening at the Hollywood Bowl last night got a surprise when the original Danny Zuko strutted out onstage.
