"As for the idea of an all-traditional programme - that fills me with horror and would, i suspect, not last beyond a couple of weeks. When are the traddies going to get it into their heads that folk music is far, far wider than just traditional music."

But, er, Mike Harding pretty much DID play an all-traditional programme! He just played the soft end of it. I'd say 95% of his show was traditional. And the exceptions were generally ones by traditional performers (eg Kate Rusby, Eliza Carthy etc)
