Last Saturday (6 April 2019), Mamma Mia! commemorated its phenomenal 20th birthday in the West End with a special finale performance that featured 13 former 'Dynamos' from the show's past seasons. The 'girl power' musical, which quickly transformed into a cultural phenomenon following the hit 2008 film, is currently booking at the Novello Theatre until 7 March 2020 in an open-ended run.
