Banish Misfortune is a traditional Irish song arranged for guitar. My version is strongly based on a recording that Richard Thompson did years ago.
I've always loved Richard Thompson's version and after playing it over the years I drastically speed mine up and I've added some alternative harmonies in a few places.
My friend Wes Lorber used to play this in his set when we did acoustic shows together. I eventually ripped him off and decided to learn it myself. Don't worry - Wes is still a better guitar player than I am.
