I was a big Nitty Gritty Dirt Band fan back in the 70's. Jimmie Fadden played a mean harp. They still play, I think some family members are mixed in now. Here is a blues trio with Fadden playing harp and percussion.
I saw them a few years ago at Casino Rama and at first I thought that the keyboard player was making "harp sounds" on the keyboard, but then I noticed that his hands didn't seem to move at the right time!!!! So I searched and searched and finaly saw that the drummer was playing from the rack!!! I was surprised. Then he came front stage later and did some solo work for about a 1/2 hour - man, he laid it down!! ---------- If it ain't got harp - it ain't really blues!!!!
