I had two spare copies, one of which was falling apart, so was good for photcopying, or transfering loose pages into a personal song book.
I took them both to last year's Miskin Folk Fest and left them on the membership/reception table, with the instruction that they could go to a good home for any reasonable donation.
Walking past 10 minutes later they'd both gone.

Worth bearing in mind for song books you no longer require, don't want the hassle of pricing/selling, and want to go where they'll be appreciated!
