The winner takes it all: Brighton, 1974

Swedish band ABBA perform their crowd-pleasing hit Waterloo at the Eurovision Song Contest in Brighton, 1974, which won them the competition.

Despite setting a unique trend, the band’s quirky costumes were a ruse for tax avoidance. It was recently revealed that the band could claim their costumes on expenses, so long as they could not possibly be worn out on the street.

Band member Björn Ulvaeus later claimed, “Nobody could have been as badly dressed on stage as we were”.
