The Chessmen were a 1960s funk-soul band fronted by Walter Scott and featuring George Semper, both of the Imperialites. They released a single in 1966 on Chess Records, "Nothing But You" b/w "Why Can't I Be Your Man."
George Semper also played with the Kingsmen (aka George Semper's Kingsmen, after another group in Portland named the Kingsmen became famous for their hit "Louie Louie"). He recorded and released his own Makin' Waves album through Imperial Records, before becoming a partner in the Jazzville nightclub on Broadway downtown in 1966. He relocated to L.A. at the end of the sixties and founded a production company called Inner City Attractions, as well as a record label, Inner City.
