C Ham - Thanks for mentioning Sam Gesser. It reminded me that I have a Penguin Eggs magazine with an extensive interview with him before he passed away. I was surprised to learn that he was a co-founder of The Record Centre on De Maisoneuve – an important asset to me when I first jumped into the world of folk music.

Bruce - thanks, I'll certainly take you up on your offer.

As I accumulate pieces of information, I'm trying to figure out a simple approach to present it in a concise and useful way. Any ideas are most welcome.
