That's right, everyone's favourite Swedish band had their humble beginnings on Eurovision! In 1974, ABBA was a little-known band representing their home country of Sweden at the annual song contest. Their performance of the future classic, "Waterloo", launched them to victory at the contest and into the stratosphere of international stardom, from hit albums to movie (and Broadway) musicals and more. Without Eurovision, we may have never had tracks like "Gimme! Gimme! Gimme!", "Dancing Queen", and "Mamma Mia". Can you imagine what a dire world that would be?
