Wait, that's it! I was just seeing track numbers on my screen, but the titles are there on what I was originally sent. And it is indeed identified as being from There's Mel...
I think it was DR George who sent me the tracks for 5 CDs, and I do have the book titles for the others. Excellent, and thank you again, George!
I would still love to know who's on all of these, if that information is out there.
