Singer/songwriter and soft rock specialist Craig Ruhnke began his career during the late '60s as a member of Toronto's Groovin' Company. After that band split up, he worked as a guitar teacher and songwriter, then pursued a solo career, releasing his first single, "My World," in 1974. The modest hit "Summer Girl" followed later that year, and his first album, Sweet Feelings, for United Artists arrived in 1975. He also recorded for A&M, and found his biggest hit there with 1980's "You're a Heartbreaker." He also recorded for his own label, Pinnacle.
