I have an original autographed Harry Chapin World Hunger Tour T shirt from a 1980 concert in Hamilton Ontario Canada.
At least I think it was in Hamilton that I saw the concert ,
can anyone advise me the dates of Harry's last concerts he played in Ontario Canada in 1980 ? I am now framing this treasure and need the concert date and location where I purchased the Tour T shirt . Can you help ?

Thanks in advance
Jim Hayes
