I think that people saying "I saw Alex at...." is typical of the man. He was on tour for much of the time!
He charged less than most professionals, and he worked a lot more, and he was often available in your locality, wherever that locality was.

I booked him several times when I ran clubs, and he never let me down, unlike some who would accept a booking and then cry off later (and late!) because they got no other booking in the area.

And could he drink whisky!
He came to our wedding ceildh. We had a day when there was nothing folky on, so he had no gigs to go to. Ah, yes. If he didn't have a gig, he would go to some local club anyway.
