February 5, 1967-June 8, 1969. "The Smothers Brothers Comedy Hour" was a breath of fresh air, but to CBS the Smothers Brothers seemed to be in the wrong place at the wrong time, with the wrong things to say.
When Tom Smothers failed to deliver one tape until a day before air time, CBS yanked the show and did not broadcast it until three weeks later (on that show, Joan Baez dedicated a song to her husband, David Harris, then serving a jail sentence for draft evasion).
