You could do a lot worse than listen to the experience of the forlks from the Lancashire Drift. In my opinion that's been one of the best folk programmes on the radio bar none for some time now. Sorry that Nic Dow is going into semi retirement: he's done a sterling job, and has been ably supported by Jan Loudner, Nic Caffery and Les Bond.
It might be an idea to invite Nic Dow onto your programme to talk about his experiences and to play some of his favourite music.

Good luck with the show.
