Founded by Karl-Heinz Rothert (vocals/bass), Keith Kossoff (a.k.a. Gunther Gruschkuhn; guitar), Uli Meisner (a.k.a. Theo Tremolo; guitar) and Toto Petticoato (a.k.a. Thomas Korn; drums) Bastard, despite their sensationalistic name, made a rather safe brand of AC/DC raunchy Rock throughout their 3 album career of Back To Nature (1978), Tearing Nights (1978) and their live set Live And Alive (1980) before they split.
Footnote: Not to be confused with Motorhead's original name.
