2008, Power trio feat. members from Def Leppard, Sex Pistols & Girl! It all started some time in 2004 when Phil Collen, after 20+ years as lead guitarist for Def Leppard, decided he needed an avenue for his material that did not fit into the classic Def Leppard mold. He hooked up with his former band mate – Simon Laffey ex-of Girl and drummer Paul Cook from the Sex Pistols.
