Vocalist Ramon McGuire formed Trooper (originally Applejack and later Winters Green) in 1972. By 1974 they had added drummer Tommy Stewart and bassist Harry Kalinsky. After hearing Trooper play, Randy Bachman signed the band for his Legend label and released "Baby Woncha Please Come Home" in 1975. The group's self-titled debut appeared the same year; it was followed by Two for the Show (1976). Soon after, Frank Ludwig became Trooper's piano player and Kalinsky was replaced by Doni Underhill. Ludwig played on Knock 'Em Dead Kid (1977), Thick as Thieves (1978), Flying Colors (1979) and Hot Shots (1979), but was then replaced by Rob Deans. The Last of the Gypsies (1989) and Ten (1991) were the last albums recorded for Warner Music, but Trooper is still active.
