Not sure if I should be replying in the "plastic Paddy" thread or this one. While playing with the "Sons of Erin" I had to wear one of those Damn sweaters. Seriously hot! 'Course had a beard as well. Oh, and no other chords except 1,4,5. (with a 2 thrown in to be radical)"Folk" is what young people play until they get a decent record deal (and can afford a band). After that it's called "roots-rock". Companies and festivals (on this side of the pond) don't want to scare off the public by calling it "folk".
