There was some great TV in the 70s too. There were some classic sitcoms. Parkinson used to broadcast interviews of interesting people who told great anecdotes and werent just there to plug there latest film, book, play, record. The Two Ronnies. Happy days.
Footnote: I used to live with a girl whose Dad was a principle singer in the Black & White Minstrals. He and his mate were still touring in the 80s and early 90s as the Minstrals but without the blackface.
