Marvin Gaye Sheffield City Hall 1976 ,just to be in the same hall as the great man was kinda spritual he even threw a Marvin strop with the band and said get it right lads or i,m not doing the show ! before going off and coming back minutes later ( could have been part of the act though ) . Also the late greats Edwin Starr with Jr. Walker at the same place both awesome and Edwin had a band called Total Concept Unlimited with him who went on to find fame as Rose Royce.
