Hosted by Julian Clary, Showtime Challenge 48-Hour Musicals brings together a cast of 100(ish) professional actors and talented amateurs, a 30-piece orchestra, and a hard-working production team. All giving up their time for the chosen charity, they pull together to produce a West End-standard all-singing, all-dancing musical in just 48 hours.

Rehearsals start on the Friday night. None of the cast have worked together on the show before this time. Then 48 amazing, exciting, exhausting hours later, ready or not, it’s showtime!
