It's always interesting listening to old reels knowing that they haven't been played for decades and not knowing what you might discover on there. Often it's just a recording of someone's record collection but if the owner of the reels was more adventurous you'll find recordings of other things, radio, tv, live recordings even. I'll be posting some of my collection in this blog. Some are complete shows, some incomplete, and some are merely fragments.
I've done my best to provide the dates but for some it's just not possible. For some I don't even know the name of the show. Probably some who download and listen may be able to help with identification.
