RUS is one of the greatest sources of lyrics and chords that I have ever found, although some of the chords are not exactly the same as I have used. We use the book frequently whenever we sit around a kitchen with our instruments. I have a whole list of suggestions but I will keep them to a few for now.
The Weight - by The Band written by Levon Helm
Dear Abby & Souvenirs - John Prine
(a lot more Prine songs as well)
I'se The B'y - tradional Newfoundland song
more songs by Paul Simon
Wreck of The Edmond Fitzgerald - Lightfoot
Farmer's Song - Murry MacLaughlin
One thing this book has been good at is including variations of the same song such as "Garden Song", "Goodnight Irene", etc. I would like to see more of this in a second volume.
