Didn't Al attend the OCA, or at least he hung out with some students there. John Layton and a guy named Brian who played an Epiphone 12-string used to hang out with him. I seem to recall that he did make a 45 of Dylan's Don't Think Twice that got a bit of radio play. I know he attended Mariposa in Orilia and the one at Maple Leaf Stadium (1965?) but I don't recall him being on the programme.
He often played the Black Swan on Housten Street in Hamilton and |I think I saw him at The Happy Medium, also in Hamilton.
