A pop and country singer-musician, and occasional lead actor, Glen Campbell was something of a child prodigy; he began playing guitar and singing on local radio at age 6. He joined a band at age 15, and later formed his own group. In 1967 he hit the big time with his mega-popular songs "Gentile on My Mind" and "By the Time I Get to Phoenix," leading to a starring role on his own TV variety show The Glen Campbell Goodtime Hour, which in turn led to roles in several films. He was first onscreen in a bit role in The Cool Ones (1967). He would make appearances in a handful of films over the years, like Any Which Way You Can and Uphill All the Way.
