Screen icon John Travolta made a surprise appearance at a "Grease" sing-a-long at the Hollywood Bowl this weekend.

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.

Released in 1978, Travolta starred in “Grease” alongside Olivia Newton-John, who died in 2022. Other cast members include Stockard Channing, Jeff Conaway, Jamie Donnelly, Dinah Manoff and Eve Arden. Made for only $6 million, the film became Paramount’s highest earner by the end of its run, with a gross of more than $130 million.
