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.

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.
