The Autoharp Guy

During the mild and warm months, Tracy and I make an effort to walk down to Port Dalhousie almost every day. The pier is a great place to sip a Tim Hortons' coffee while gazing out into Lake Ontario. When the sun's out, there's a guy who is pretty much guaranteed to be there, sitting on the same bench every day, over on the east pier, wearing only shorts and playing his autoharp. He's not busking, he just seems to be playing for his own entertainment. Regular visitors to Port will know who I'm talking about. Who is this guy and what's his story? I'm intrigued.
