Broadcasting live from a 1950s style high school prom in the UK, Alan Carr's Grease Night is a one-off entertainment extravaganza hopelessly devoted to all things Grease and 50s Americana. Featuring some very special famous faces, including the original Frenchy, Didi Conn, and Katherine Ryan. There's dancing, dating, plus some big audience surprises. At the end of the night two lucky prom revellers win the ultimate high school accolade of being crowned Prom King and Queen.
