Canadian Glenn was a bit of a maverick. Taciturn and moody, he gave his last professional concert in 1964 at the age of 31 - because he hated performing.
He was also enigmatic and good-looking enough to make perfect hero fodder - as this famous image from Life magazine shows.
I've forgotten how to download the Youtube link (I must ask the nice man at the Apple shop) - but go and listen to his music if you don't already know it.
Or do you?
