Now that you mention it, I bet some of them DO have chord letters marked! (I'm using the little guitar chord charty things as cheaters for uke..to familiarize with chords I don't normally use)

I'm really not familiar enough with the melody of many of that type of song to get much use out of them.
I know a lot of folks find delight in the lyrics and/or style..but I truly have no use for these books. If there's no taker, they'll end up in a box in the basement (until they're too dampened to keep) because I can't hardly stand to pitch readable songbooks.

This just seemed like a good place to offer them.
