I met him once.
I was working cashier at the downtown Sam's in Toronto (a record store) on the evening shift, and musicians often dropped by the store after a concert at Massey Hall, which was only a few blocks away. Our third floor was famous - crammed full of old and rare stuff that had long fallen off the charts if it had ever been on them.
He bought a couple hundred records, and I checked him out. It took forever - this was long before the days of barcodes and electronic cash registers - and we chatted the way you do, cashier and customer. Says something, I think, that someone as famous as he was, after a tiring concert, would bother to be friendly and pleasant to the cashier.
