Can't forget Mays & Cappy's -
Bob Mays, proprietor of a bona fide record collector's store. His shop was on E. 8 Mile near I75, first on the eastbound side, then, for a few years until he was finally forced to close, on the westbound side almost across from the original.
When I went in around 1968, Bob looked old to me [[most everyone over 30 looked old to me, I was 18) and seemed to drink "a bit." He had a solid grasp of jazz records and their worth. I bought my first 78s from his store - a Bird Dial, and a Tatum Decca - and went back many times over a 30 year period, until I actually had most everything I wanted due to the advent of CD's.
Bob is one of those guys who seemed designed for and destined to sell used records. He would have looked odd selling groceries, or car insurance, but was totally right for the record job. Thin as a rake, long bushy beard, smoked a lot, always dusty boxes piled high in corners and most everywhere else in his modest sized space. To borrow a quote about Duke Ellington, Bob looked like he'd seen it all, and done most of it. He still has a table at record collector shows.
Now Cappy was different - stocky guy rough voice, friendly but didn't take crap from anyone. Always thought Cappy was an ex motorcycle gang member for some reason - just had a slightly menacing air about him, but once you talked with him for a while he turned out to be a really nice guy. And he knew his records, especially his Detroit records. I asked him once if he had any disco records, and he looked at me in disbelief before bursting into laughter for a solid minute. I wasn't joking, but I was too insecure to fess up and tell him I wasn't joking, and we moved on to other topics.
Cappy had to pack up most of his 'special collection' for some reason which I've forgotten, and wasn't in a big hurry to unpack them - if you've ever moved a lot of records, you know the effort involved. Cappy closed his shop a few years ago, and I that was a major loss for Det record collectors. I only hope he gets the chance to channel his amazing knowledge into a Det business of some sort - maybe selling records?? LOL.
