Re: Cowboy songs out of copyright:
I know I’m replying too late for this book, Cowboy Concertina, but hopefully there will be a volume two. There is a book by Katie Lee, “10,000 Goddam Cattle: A History of The American Cowboy in Song, Story, and Verse.” She collected many old cowboy songs, some of which I’ve never seen elsewhere. I bought a copy years ago, and still sing some of these to my children. Some are classics, and some are versions I’ve only seen in this book. I imagine most are out of copyright.
I hope you can bring these songs back to life again with some concertina tunes.
PS. It turns out she’s a legend in the Southwest.
