Mamma Mia! in London
Sing your heart out to Mamma Mia!
Mamma Mia the film, directed by Phyllida Lloyd with choreography by Anthony Van Laast, was the highest grossing musical film in the world… ever. And the musical version is a smash hit to end all smash hits. Mamma Mia The Musical has already been seen and loved by more than forty five million people across six continents since it first opened in 1999. With music and lyrics by ABBA’s Benny Andersson and Björn Ulvaeus, joined by songwriter Stig Andersen, this Olivier Award winning adaptation of British playwright Catherine Johnson’s book is an on-going runaway success.
Mamma Mia! - The story
Mamma Mia is a touching tale about a wedding on a sunny Greek island. Sophie, the bride, has nobody to walk her down the aisle and her mission to find her father uncovers three very different potential candidates from her mother Donna’s fascinating past. All three ex-lovers return to the island, where they first met Sophie’s mother two decades earlier, and Donna is transported back to re-experience the memories of her rebellious, carefree youth. The story of the wedding unfolds, infectiously funny and light hearted, told through twenty two of ABBA’s greatest hits.
Mamma Mia The Musical continues to deliver love, laughter and friendship to delighted audiences from all over the world. Taking its rightful place as one of the West End’s greatest triumphs, it’s popular with people of every age and taste.
Mamma Mia song list
Everyone loves ABBA tunes, and Mamma Mia The Musical contains twenty two of their biggest and best-loved chart toppers. "I Have A Dream", "Honey, Honey" and "Money, Money, Money" take to the stage, with "Dancing Queen" also being featured in the show.
The music delivers laughter and tears in equal measure, it’s one of the best feel-good West End shows to hit the London stage. Mamma Mia The Musical is an all-singing, all-dancing extravaganza that’ll leave you feeling uplifted, inspired, and determined to buy a copy of ABBA’s greatest hits as soon as the shops open the next day!

It was full and lots of young foreign student group who really appreciated it. Not a lot of knee space in our seats row A of balcony but others seemed OK.

Brilliant show, Stevie and Tobias were fantastic, it was their first week and you would think they’d been doing it for ever. Would have liked Stevie to have been allowed to keep her Scottish accent, was disappointed that it was felt necessary to change it. All the cast were amazing, special shout out for Mazz as Donna, what a voice. Defy anyone not to feel good after watching it. Choreography superb and all the cast looked like they were one big happy family. Slightly spoiled by some girls in front of us singing along (badly) too loudly, all we could hear was them.

We were a family party of 5, spanning 3 generations, and all thought the show amazing and well worth the trip down from Scotland. Sometimes a cast will hold back in matinees, knowing they have an evening performance to come, but there was no sign of that here. An excellent show from start to finish. Special mention to the band as they are usually missed in reviews. Having played in bands for many shows, I appreciate what they do and this one was outstanding.
