"...There must be others out there whose contributions would make a refreshing change..."

John, there may well be. But the chances are they would not be recognised by the average C5 viewer, no matter what their qualifications. And I repeat my sentiments from above: None of us on this forum can claim that our personal tastes are definitive. So if you don't consider BB a folkie, good. I would not try to change your view. Just don't try to persuade me that this is the only valid view. You can always write to the BBC and take this up with them.
