From Les années psychédéliques: 1966-1971, which was originally released as a series of 12″ records highlighting some rare psychedelic soundtrack cuts from Gainsbourg. This one was done with Jean Claude Vannier and was the theme song for the 1969 French film, La Horse.
France Gall – “Laisse Tomber Les Filles”
1964 song (meaning “forget the girls”), composed by Serge Gainesbourg and performed by France Gall. Catchy as hell.
