Coyote Breath,

You either get Bluegrass or don't. Unfortunately it is the vast majority who don't and they seem to feel the need to pass comments. I fully expect Letterman to say some stupid things, and that a lot of people will find them hilarious.

The good news is that the success of the O Brother soundtrack will bring a lot of people to bluegrass. Some will stay with it as long as it's in fashion, others will stay and help keep it alive.
