LIONHEART was formed in late 1980 by Dennis Stratton (lead guitar/backing vocals, ex-Iron Maiden), Jess Cox (lead vocals, ex-Tygers of Pan Tang), Steve Mann (lead guitar/backing vocals, ex-Liar), Rocky Newton (bass guitar/backing vocals, ex-Wildfire) and Frank Noon (drums, ex-Def Leppard). The band began playing gigs including regular shows at London's Marquee Club but had problems maintaining a consistent line-up. The core personnel of Dennis, Steve and Rocky remained but various singers passed through the band including Rueben Archer, John Farlham and Bob Hawthorn. They eventually settled as a 4-piece with Dennis and Rocky sharing lead vocal duties. The drummer's stool was variously occupied by Les Binks (ex Judas Priest), Niko McBrain (ex Trust and subsequently Iron Maiden) and Clive Edwards (ex Wild Horses).
