I'm not sure i like the idea of well adjusted, well behaved, nice, folk musicians of any age

And if they are well adjusted, well behaved and nice, at least they ought to have the good sense to hide it...

I was reading a highly entertaining interview with the (old enough to know better) John Lydon in Mojo recently (the one where he 'admitted' to liking Steeleye Span!) and it did occur to me that folk is sorely lacking in pantomime villains. Any contenders?
