Swedish pop group ABBA, made up of Agnetha, Björn, Benny and Anni-Frid, rose to global fame in the 1970s after winning the Eurovision Song Contest with "Waterloo". With timeless hits such as "Dancing Queen", "Mamma Mia" and "The Winner Takes It All", ABBA became one of the most successful pop groups of all time. Their catchy melodies and flamboyant costumes turned them into pop culture icons. A fun fact is that ABBA often wore flashy, glittery outfits because Swedish tax law only allowed clothing to be deductible if it was unsuitable for everyday wear.
