The Carol Burnett Show

The Carol Burnett Show was a sketch comedy television show starring Carol Burnett, Tim Conway, Harvey Korman, Vicki Lawrence, & Lyle Waggoner. It originally ran on CBS from September 11, 1967 to March 29, 1978 for 278 episodes. The show became known for its closing theme song, with the following lyrics:

I'm so glad we had this time together, Just to have a laugh and sing a song
Seems we just got started and before you know it, Comes the time we have to say, 'So long

Vicki Lawrence was the only cast member, other than Burnett, to remain with the series for its entire run. Tim Conway, though well remembered for his appearances on the show, did not become a full-time cast member until 1975. Harvey Korman left the show prior to its final season; he was temporarily replaced in the fall of 1977 by Dick Van Dyke. Original cast member Lyle Waggoner left the series in 1974 to pursue a dramatic acting career and the next year was cast in Wonder Woman.
