After greeting the other cast members and director Randal Kleiser, John Travolta turned to the cheering crowd: "LA? I thought you were going back to Australia," he said, echoing a classic line from the film. The artist then told his fans he was feeling "rock and roll and all that" and sang along to "A-womp-bop-a-looma a-womp-bam-boom?" from the song "We Go Together." "Enjoy the show, we love you!" John Travolta concluded, before leaving the stage. The next day, the Saturday Night Fever actor thanked the audience on Instagram: "Nobody knew. Not even the actors.
