The show will follow seven celebrities as they undertake musical theatre masterclasses from choreographers and vocal coaches and prepare to perform on the London Palladium stage.

Supported by a West End chorus line, the famous acts will be judged by both the panel and a theatre audience, with the latter deciding who deserves to win at the end of each night.

All Star Musicals will also feature performances from John Barrowman, Elaine Paige and other critics.

“I can’t wait to bring something fabulous to the TV screens, working with new friends and teaming up with some special old friends, this should be a great night of entertainment,” commented Barrowman on his new role. “Let’s make All Star Musicals fabulous.”

Elaine Paige added, “All Star Musicals is the perfect opportunity for me to channel two of my greatest passions – musical theatre and mentoring.

“I’m looking forward to following the celebrities on their journey to performing on London’s most prestigious stage, and of course it’s an added bonus to have a front row seat on the night itself.”
