Battlezone performed a club tour of America in 1987 to promote the début "Fighting Back", but musical differences, arguments and physical fights within the band led to the departure of John Hurley and Bob Falck after the first tour. According to Di'Anno's book "The Beast", Hurley had become an "egomaniac" and the drummer Falck a "liability", so they were thrown out the band. Their places were taken by ex-Persian Risk members Graham Bath and Steve Hopgood respectively, following the tour's completion.
