First, ABBA rises to stardom in their native Sweden with Ring, Ring. They then win the Eurovision Song Contest with Waterloo, which is also recorded in English, French, German, and probably Spanish. Twenty-five years later, the English-language musical Mamma-Mia premieres in London and subsequently spreads through large portions of the world not yet civilized enough to ban fluorescent pink tuxedos or platform shoes.
And now, the musical is being translated into Swedish and auditions are being taken for a scheduled opening in Stockholm on 12 February 2005.
