We all thought we could change the world with songs back in the sixties. Joan came to Australia in the late seventies and played in Melbourne at an open air concert, just her and her guitar. It was 40 degrees celsius which is over 100F and she was really feeling the heat and the flies but she still gave three hours of the best concert I ever saw. I wish she'd come back again. We don't get a lot of news down here. I'm delighted to heart that she's still performing.
