 Dancing Queen from ABBA, the Swedish quartet made up of two men and two women. One of those ladies, Agnetha Falskog, she was the blonde, and she told us how her group became ABBA. You know, that's our initials of our first name. My name is Agnetha, and the other girl is Anne-Fried, and the two Bs are Benny and Björn. So that would be ABBA.
