This is one of those tunes where you could go on playing it forever, it’s so good.
Play a D chord through the first A section then at the next A section use the written chords. Tempo 200bpm or more.
Gorgeous little tune.. I know it as Jackson’s Morning Breeze though. Learnt it from the playing of Andy Davey
