One of the members was Benny Andersson (later of ABBA fame), another was Sven "Svenne" Hedlund – and they later wed. She joined her husband by becoming a member of Hep Stars and later as a singer duo Svenne & Lotta in the 1970s, called "Sven & Charlotte" in certain countries.

Svenne & Lotta competed in the Swedish heats for Eurovision Song Contest, Melodifestivalen, in 1975, with a song penned by the men of ABBA, called "Bang en boomerang", and also recorded the song in English and had a hit in several European countries with "Bang a boomerang".

Svenne & Lotta went on to become one of the best selling groups of all times in Denmark, and even recorded a single in Danish.

Hedlund and her husband toured Sweden as a duo as well as solo artists until their divorce in 2014,[2] and were considered a cult act.
