I have a book that is a pretty good sourcebook-for amatuers (sp?) like me anyway...It's called _Gonna Sing My Head Off:American Folksongs for Children_. Collected and arranged by Kathleen Krull. I bought it back in the early 1990's, hopefully it is still available somewhere.

And Steamship,so that you might rest easier about the state of education, I'm surprised I can sing for my final also. But I do have to provide historical context and discuss the societal forces that were prevalent at the time the various songs I am singing were written. But I will do a better job with sentance structure-I'm a bit flustered right now, I get to take my oldest to get his driving learners permit-YIKES!
