Thanks for all the great ideas/ info! This is much better than I hoped for (I was expecting a very small number of replies!). Currently I would like to look at folk music and dance in its current incarnation, how it is done at festivals and in clubs across the UK and by the big artists plus a little about the history of traditional music. I would want lots of humour, colour and noise to show people that it's not somthing dull which we should be ashamed of but a celebration of our cultures.
I hadn't thought about Stephen Fry as a presenter but he would definatly be the type to put the programe (is that really the American spelling?) across.
