The San Patricios -- the international brigade you've probably never heard of (half a century before the Spanish Civil War).  This version is from Live in Rostrevor (2016) with Lorna McKinnon on harmonies.

St. Patrick Battalion

Singer/songwriter, writer, podcaster (on Spotify, Substack & Patreon), libertarian socialist, dad, lover of life.

I'm a radical political activist/singer/DJ who is obsessed with getting as much music as possible on film which would otherwise be lost in the maelstrom of history.....

I highly recommend that you check out the festivals of eastern PA, ie., http://www.jibberjazz.com , Trails End, Bear's happenings, etc....

And of course the Gathering Of The Vibes - http://govibes.com ....

You can listen to some of the music I post if you want (the music isn't mine), idk
