Hmm. I heard that, and thought "how long before there's a hundred-post thread on Mudcat about a 2-second off-hand comment?" Answer seems to be: not very long. :-/
Is Matthew Parris allowed to say he doesn't like trad folk music? If not, why not? And if he'd said the same about rap, would anyone here be complaining? Or opera?
FWIW, I also wasn't greatly keen on the singer in that clip, and the prospect of an entire evening of it would fill me with as much dread as it probably would Matthew Parris and Kim Howells. That's not a judgement on the song but the singer - it made my teeth itch like fingernails down a blackboard. Thankfully all folk singers don't sound like that.
And interestingly the same programme also mentioned the disproportional funding of opera against other traditional English music such as brass bands.
