Trouble is, Barbara, while it was Peter Yarrow who got busted, it was family man Noel Paul Stookey who wrote and performed "Talking Candy Bar Blues." Stookey is probably the straightest of the three - heck, his wife was just ordained a minister.
While "Talking Candy Bar" is about getting busted with underage kids, I think it's strictly a humor piece. The song was recorded (by Stookey) in 1965, and Yarrow was arrested about 5 years later.
I've seen things in print that said that it was Stookey who was arrested, but that's not true. I found fairly good documentation in the NY times archives that showed that it was Yarrow who got arrested, not Stookey.
I suppose there will always be people who read things into songs, but what the heck would be wrong with writing these songs just for the fun of it? If their purpose were to have hidden meanings, I think they would have been a little more clever about it.
