I picked up a 10CD set of the 1989 concert (I think it was 89 - can't remember) from KPFT during one of their fund drives about 2 years ago. Amazing recordings. EDIT: was 1984. Link (and no, I did not pay 500 bucks for it)
I have an LP of Weldon "Juke Boy" Bonner at the 1983 Juneteenth Blues Festival. Used to go every year from 1977 through the mid 80s.
Black? Sorry ... let me be "politically correct": "African-American"? The real question is: What parade will you be going to?
Another reason to celebrate...well, there are no festivals that I know of up here... I plan on taking the kids to the movies or museum tonight...
