Two great music shows from the 60's:
The Smothers Brothers Comedy Hour- Tommy and Dickie Smothers were great on their own, satirizing the folk boom of the early 60's. When they got a chance to host their own variety show, they managed to give exposure to some great acts that would not have fit too easily in mainstream tv, like The Who , Jefferson Airplane, etc. They tangled with the censors and top brass at CBS, which ultimately led to their show getting cancelled.
But for a while, they were really something.
Beat Club- this German show ran from 1965 to 1972, and any musical act who was anybody appeared on it at one point or another. I got my first exposure back in the 80's, in the early days of MTV they showed clips from this show as Closet Classics (mostly to satisfy old geezers like me). Great live performances (although from 1967-69 most were mimed) against psychedelic backdrops, this show was untouchable. not only are many great moments posted on youtube (check out mybeatclub) but there are a great number of DVDs out there. Groovy.
