On the 6th of April 1999, exactly 25 years after ABBA had won the Eurovision Song Contest with the song Waterloo, the musical Mamma Mia! opened in London. The funny and appealing love story, based on 22 ABBA classics, became an immediate success. Arranger Peter Kleine Schaars has selected five of the most famous titles from the musical, added the hit Waterloo and used his musical imagination. The result is a catchy ABBA medley that will appeal to young and old.
