In 1967, the Smothers Brothers Comedy Hour started on CBS. It ran from 1967 to 1969 and evolved into daring political satire of the Vietnam War era. In 1969, just as President Richard Nixon was beginning his administration, they were fired by CBS. Here the brothers are explaining how their show was cancelled.
Tommy mentioned that CBS objected to Joan Baez explaining that her then-husband, David Harris, went to prison for resisting the draft. Here she is in San Francisco in 2017.
Baez celebrated her 76th birthday in January, and as you can see, she is still protesting the issues of today. Tommy Smothers is 80 years old. Dickie Smothers is 77 years old. They retired from touring with their act in 2010.
