I heard of Hyperdrive but not the first one and am pretty good on obscure TV.
Black Books is another favorite of mine.
It Ain't Half Hot Mum was VERY popular on British TV you probably have not heard of it for the "politically correct" decision that it should never be shown on TV ever again!
I forgot to add “It Ain’t Half Hot Mum” was written and produced by the same people who did “Dad’s Army”
