Mamma Mia! celebrated its 25th anniversary on 6 April 2024, making it one of the longest-running musicals in West End history. Since its premiere in 1999, the show has become a global sensation, with over 70 million people having seen it worldwide. The musical has grossed over £4.5 billion at the box office and inspired two successful films,

Produced by Judy Craymer, Richard East, and Björn Ulvaeus for Littlestar in association with Universal, the show features ABBA’s timeless hits, written by Benny Andersson and Björn Ulvaeus, and the story by Catherine Johnson. The show is directed by Phyllida Lloyd, with choreography by Anthony Van Laast, and design by Mark Thompson.

The musical has broken box office records in each of its London venues and continues to enjoy success with ongoing tours in the UK, North America, and beyond. As part of its 25th-anniversary celebrations, ITV’s Mamma Mia! I Have a Dream saw Stevie Doc and Tobias Turley join the London production as Sophie and Sky earlier this year.

Doc and Turley have also set their final performance dates.
