That was a great song. Though to me it seemed more bluegrass than blues.

It could be played in any type of music.That's up to the musician.I thought of it as a Blues,but you've got a good point;it could very well be played as a bluegrass song.Or heavy metal,if so desired!

That is so very true. Mind you its also true of just about any song. Wasn't there an SNL skit featuring a Sinatra-style version of Billy Idol's White Wedding?
