Nancy, That's great sleuthing. The country music disc jockey was indeed Cactus Jack Call. I'll have to send you an invisible facsimile for your effort.

Kat, Does this mean I have to go hunting in the archives again?

Art, I remember showing up at the OTSFM around the beginning of 1963 (that's about the time I arrived in Chicago) and that's probably where I acquired the copy of Sing Out! I referenced. I'm sorry to say, I didn't know about Horton Barker concert you mentioned. That would have been a real treat.
