I'm a producer of radio comedy shows, and if you like that sort of thing, you could tune to Radio 4 at 23:00 on Tuesday nights for Cowards, an excellent sketch show written and performed by The Cowards.
Or, try BBC7 at 22:30 every Wednesday night when you can hear a series I made called Witty & Twisted which features some newer but no less lovely comedians appearing in their first ever radio programmes. They include Stuart Goldsmith & Sam Hutchinson, Miriam Elia, Lee Derbyshire, Andrew Wallace, Roop Jones & Tom Bowker, Stephen Carlin, Mark Steele (not that one), Caravaggio's Travelling Circus, James Kettle, Gareth Gwynn.
