Thanks Bob!

I appreciate it.
Joe reminded me that you provided the missing bits to the trail I followed. I forgot to say "Thanks" but thought I had.

Even more importantly, Thanks for posting these solutions to the puzzle here for other folks to find.

There seems to be a break in information of the late folk revival. So many folks who performed in the 70's & 80's remember the situations surrounding events and specific songs that little of this information is written down for a younger generation to find. After my generation, it all goes to searchable digital discussions. I appreciate references like this that allow us to bridge the gap.
