Magnum are a British progressive rock band from Birmingham, England. Formed as a four piece by Tony Clarkin (guitar, songwriter), Bob Catley (vocals), Kex Gorin (drums) and Bob Doyle (bass) in order to appear as the resident band at The Rum Runner night club in Birmingham. Magnum have undergone several changes in personnel over the years; however, the core of Catley and Clarkin remain. Magnum's most notable success during their early years was Chase The Dragon in 1982, which reached #17 in the UK Albums Chart and included several songs that would be mainstays of the band's live set, notably "Soldier Of The Line," "Sacred Hour" and "The Spirit".
