As for 78 DeeJaying, a friend of mine told me about a guy in Burlington, Vt. who had a collection of 78s and a windup Victrola. Supposedly, he played requests (within the repertoire of 78s he had with him at the time) for passersby. I'd looked forward to hearing him do his thing, but by the time I got to Burlington, he evidently was no longer around.
