In 1975, Earl returned to play keyboards, drummer Peter Sullivan joined and percussion player Joe Rush, part-time member of the band in earlier days, also came back for a while. The group's line-up continued to change. Among those who have played with them are bassist Bob Daisley, drummers Dave Bidwell, Paul Hancox and Boris Williams, guitarist Dick Middleton, keyboard player Sev Lewkowicz, and keyboard/accordion player Steve Jones. They have remained popular throughout Europe. Mungo Jerry was the first western band to have live television gigs in all countries behind the Iron Curtain.
