A good song remains so regardless of who sings it provided the understanding of it is conveyed by the performance.

Anyone ought to be able to sing anything they like if they do it with perception and taste or in some cases, if it's funny, without taste.

I like the mixing of cultures, creating jazz, folk, pop, even so-called classical music.

I'd love to hear what Yoruban singers do with the Celtic, English, Appalachian or what have you music.

There is nothing holy about being a folkie. They can be bigoted, narrow-minded, pretentious, and ignorant people about music as anyone else.
