25 years after ABBA won the Grand Prix d'Eurovision with the song Waterloo, the world premiere of the musical Mamma Mia! took place in London. The rousing love story, based on 22 ABBA classics, quickly became a great success. Peter Kleine Schaars chose the six most famous titles from the musical, added the world hit Waterloo to them and let his musical imagination run wild. The result is a sophisticated ABBA medley that appeals to young and old alike.
