"I would hope that they would be songs that are fairly well-known. the idea is to make a third collection of songs for people to sing, rather than presenting a list of obscure songs that people may never sing."

I would hope there would also be obscure songs that people would sing, if only they knew those songs existed. The great thing about the two books is that not only do they have a lot of my old favorites but that when I heard a fine song I had never heard before there was a good chance I'd find it in one of the books. I think people would like, and would want to sing, the songs I listed way back at the beginning of this thread – the singers and the songs just need to be introduced to each other.
