On BBC 4 tonight (TV not radio), at 10:30, Flight of the Conchords season 2 gets underway. If you've never seen the show, give it a go. It's about two musicians from New Zealand trying to make their way in New York - along with their incompetant manager, Murray. They're regularly stalked by their fan, Mel.
Of course, I've not yet seen season 2 (though it has gone out in the States) - but having seen Season 1, I'm looking forward to it.
