A 1970's TV renaissance on the horizon?

Someone sent me this link today

It made me laugh, but also reminded me of watching this when originally broadcast with my parents. I enjoyed watching them laugh, but I didn't understand why. I certainly now recognise its great quality.

However I understand various broadcast companies are forcing YouTube to remove clips like this because of copyright infringement. A shame if they do, because more than likely many people will get to enjoy them properly second time around, and buying the DVDs because, not in spite of, YouTube.

Maybe we'll even get to see them on the screen again ?
