In the 1970's, I saw him perform in Boston. It was a New Year's Eve show. I went to the show with my parents, and was too young to appreciate what a legend I was watching.
I got to spend several minutes visiting with him in a CA airport while both waiting on planes. Pleasant visit. He was headed to a preaching gig and I was headed home. One thing that struck me was his HUGE hands.
I remember my dad telling me he was the greatest performer he'd ever seen. And he saw Elvis, Buddy Holly, Jerry Lee Lewis and a bunch of others in the 50's.
