The blues stuff he did? Meh. The big band jazz he did? Love it!
I think it was Stuart McLean who mentioned going by his house, and in his basement he had 30,000 old 78s. You mention some amazingly obscure 1920s ragtime track or a rare 1930s big band track, and he would go over to a spot on the shelves, and pull out the exact record. Knew where everything was. Which, given that whole lack of eyeballs, is rather remarkable. And I though my record collection was organized.
