Recently I attended a concert by "A Band Called Honalee", a tribute group to Peter, Paul, and Mary mainly, though they also performed a few tunes by other groups from the '60s. (They were good; check them out if they come to your town.)
I was a bit surprised that I was the only one there in a tie-dyed shirt (and a headband). Not exactly CDing, but not exactly mainstream. I had fun.
