Jackie Washington is a national treasure.
And we should be clear for any Americans reading this thread, we are talking about the Canadian Jackie Washington, not the Boston-area musician. The Canadian Jackie Washington came up as a jazz musician in Hamilton, Ontario, and has been on the music scene for about 80 years. He knows over 1400 songs, lots of obscure old swing tunes, and since the mid-70's has performed at a lot of folk festivals across Ontario and Canada.
There's nothing better than sitting at a folk festival stage where Jackie is holding court.
