Glen Campbell received quite a following during his stint on "The Smothers Brothers Show". With his easy manner and popular music, Glen won quite a TV following leading to his own CBS series, "The Glen Campbell Goodtime Hour". Glen had two hit songs on the charts when he got the series, they were "Wichita Lineman" and "Galveston". The series was filled with comedy, solos, and a very easy-going down-home friendly manner which endeared him to the masses. Composer-singer John Hartford wrote the theme song for the series, which was "Gentle On My Mind" and made frequent appearances throughout the show's run.
