You may be able to find it on google books section I found a lot of great material on the weavers including interviews.

I came across a little something from a book where They were talking about how they were going to preform Tzena Tzena Tzena I don't know if it was Snader or not but they wanted Ronnie to wear a apron and pull bagels out of it while singing the song. Well of course she DID not wear it. that's the kind of thing they had to put up with ignorance like that.
