I've only just come across this site & have today posted my own stab at a guitar chord sequence for this lovely song. These are based on the melody and lyrics performed by Robin Hall & Jimmie MacGregor on their 1969 album 'One Over the Eight'. Not sure how 'authentic' their version is but I do like it, particularly with their vocal harmonies. It's the only version I know. I've posted it to the original 'Tatties and Herrin'' thread started back in 2000.
