Around 6,000 fans of Singapore’s Class 95 turned up at Retrolicious on Saturday to see 80s icons Belinda Carlisle, Rick Astley and Bananarama.

But they got more than they bargained for when two of the station’s personalities dressed up as Sandy and Danny from the hit movie Grease and took to the stage.

DJs Jean Danker and Mike Casem, who host the evening drive show Cartunes, donned their best all-black attire to appear in front of fans at Fort Canning Park.

The super-tight outfits were similar to those worn by John Travolta & Olivia Newton John for the song You’re The One That I Want.

Class 95’s Morning Express team Glenn Ong and Joe Augustin also dressed up, taking inspiration from The Blues Brothers.
