the band's members were parts of other groups from the rock scene of northern france. they were in good friendship when the opportunity of recording the "popcorn" cover was given to them by paul de senneville of (az records) in 1972. they were chosen because of c. lerouge's incredible ability in using a minimoog. commercial success (700,000 copies) gave the band an opportunity to release two other singles ("carmen brasilia" and "royal summer"), even before they were signed in 1973.
