I still have a small collection of song books that I bought and used when I was in the Guides here in the UK. There used to be day-long courses in campfire singing as well, so they could teach some of the more complicated harmony songs - and I did a badge in campfire songs. The songs still surface in my repertoire when I'm working with children so yes, it's worth remembering just what an immense contribution this whole practice has made to singing in general.

I even heard tell that Paul McCartney was renowned for his Elvis impersonations when he was a Boy Scout (a little known part of his history, but this story came first hand from someone who was in the Scouts with him).
