The cast of ‘Grease’ go together like rama lama lama ka dinga da dinga dong when it comes to celebrating the legendary musical movie. John Travolta and Olivia Newton-John, who played the film’s love birds Danny and Sandy, were among those present at a 40th anniversary event celebrating the hit film.

The ’70s musical rom-com was screened at the Samuel Goldwyn Theater in Beverly Hills last night.

Ahead of the event, Travolta and Newton-John were spotted on the red carpet snuggling up together, looking smiley, and even doing the legendary box step (a move Travolta recently taught Jimmy Fallon how to do on his talk show) from the movie’s ‘You’re the One That I Want’ number (which the director of the film, Randal Kleiser, recently broke down in detail).

Also present at the event were Kleiser and two more stars of the film, Didi Conn, who played beauty-school dropout Frenchy, and Barry Pearl, who played wisecracking T-Bird Doody, as well.
