I don't know if this linking is allowed on here but for those with a Spotify (online music site) account (either free with ads or paid ad free) you will find:

The Very Best of Rambling Sid Rumpo
Kenneth Williams
24 tracks

Sadly I don't think Spotify is available in the US yet.

On there you will find lots of the BBC musical stuff ~ oh and also Bert Weedon, Marty Feldman and lots more Kenneth Willams

I grew up in a family where listening to BBC radio, especially the comedy shows (it was how I learnt about different kinds of humour) was part of our daily routine, Sunday teatime was 'Sing Something Simple' with the Cliff Adams Singers ...... and when we finally got a TV there was Robin Hall and Jimmy Mcgregor singing folk songs which was accepted by everyone we knew as 'normal', sometimes we kids would try singing them in the playground the next day.

Right I''m off to brush up on some more black & white nostalgia ......
