When people talk about bands that have sliding doors for all kinds of members to jump through, back and forth, Whitesnake and Rainbow are the most talked about. Why UFO seems to be unnoticed in that department is beyond me because if there’s one band that has been a band member roller coaster throughout the years, then it’s UFO. The band was formed in 1969 by singer Phil Mogg and bassist Pete Way together with guitarist Mick Bolton and drummer Andy Parker and the four of them released their self titled debut the following year and that line-up stayed together for 1971’s UFO 2, but for their third album Phenomenon (1974), Bolton had been replaced by guitarists Michael Schenker and Bernie Marsden, the latter only played on two songs on that record before he was gone. Marsden later joined David Coverdale when he formed Whitesnake in 1977. That somewhat stable line-up kept intact for four more albums with the addition of keyboard player / rhythm guitarist Paul Raymond, Force It (1975), No Heavy Petting (1976), Lights Out (1977) and Obsession (1978) – all hailed as true rock classics today, before Schenker left after a lot of fighting within the band, mostly created because of drink and drug use. The last thing Schenker played on was their now classic live album Strangers In The Night (1979). He went to form his own band Michael Schenker Group (MSG). The band replaced him with Paul Chapman for the albums No Place To Run (1980) and The Wild, The Willing And The Innocent (1981) before Raymond left and was replaced by Neil Carter for 1982’s underrated Mechanix, but by Making Contact in 1983, Way had also departed, leaving Carter to play the bass on that album as no permanent replacement had been chosen for that record.
