Swedish duo consisting of Svenne Hedlund and Lotte Hedlund (Charlotte Walker). They are called Sven & Charlotte in some countries.

Svenne Hedlund was lead vocalist of the successful Swedish group The Hep Stars around 1960.

Charlotte Walker (born 1944), was a former member of the American group The Sherrys, later moving to Sweden and becoming a member of The Hep Stars, adding female vocals, in 1968. She married Hedlund, and shortened her name.

The couple formed the duo after The Hep Stars parted ways and recorded several albums for the Polar label. In 1975, they took part in the Swedish selection (Melodifestivalen) for Eurovision Song Contest with the Swedish, Bang En Boomerang, written by Benny Andersson (former The Hep Stars bandmate) and Björn Ulvaeus of ABBA (who, as well as Svenne & Lotta, recorded an English version). Svenne & Lotta came third in the selection.
