Asterix was a direct predecessor of Lucifer's Friend; released one (eponymous) album in 1970. Technically, this was the first Lucifer's Friend album, only under a different name. Also, one single was released featuring a slightly altered line-up, without John's involvement.
Peter Hesslein began his musical career way back in 1963 with a band called the Giants. Peter Hecht and Dieter Horns were both members of a group known as the German Bonds, from 1965 onwards. Peter Hesslein joined the Bonds in 1968 which survived until 1970. At this point the various members took up the study of graphic design in an attempt to forge more sensible careers.
But the call of rock'n'roll was too strong and in late 1970, the ex-Bonds men, together with Joachim Reitenbach, decided to record a new album. They needed a lead singer and eventually found John Lawton who had been with the group Stonewall. The new band released their first album 'Asterix' in 1970 under the same name before they change to Lucifer's Friend.
