I was in Canada during that period, watching the CBC. In addition to the programs mentioned, The Two Ronnies was good, as was the precursor to Amerca's Three's Company, Man About the House. But I have to confess, my guilty pleasure was
Clochemerle.
Ah right! The Two Ronnies was another great one! Back in the 90’s/early 2000’s, I remember watching British Comedies on Sat. nights on PBS. Keeping Up With Appearances and Two Fat Ladies were among my favorites.
