I keep forgetting to check the BBC Radio 4 Comedy site. They have some great stuff to listen to. Right now I’m listening to Laughing at Dingoes, which is Mark Little’s documentary on Australian humour. Ross Noble goes Global is something else I like, too. There’s lots of stuff there, but you need to check weekly because many of the programmes don’t get archived, presumable because the BBC want to sell them on tape and CD.
