Good Rockin' Tonite was a Friday night music program produced in Vancouver, featuring music videos, in-depth interviews, contests and countdowns of the week's most popular singles and albums. The original host, Terry David Mulligan, conceived the program with producer Ken Gibson, who was behind the CBC's last rock-music effort in the '60s, (Let's Go) which helped launch the careers of a number of Canadian groups. Mulligan left the show in 1985 and was replaced by Stu Jeffries. The series moved to Saturday nights in its final season.
