"Fiddle Box Carrier" on Hayden Duet Concertina
It's been a while!
Been busy with other things but this lovely tune I heard from a musician traveling from Aberdeen, forced me to sit down and record. attributed to Catherine Brown (Aberdeen).
See my transcription of what I heard.
I added simple repetitive chords for left hand.
