He did, PMB! I believe it was named the Shand accordion. I could be wrong but I believe John Kirkpatrick plays one. Talking of Shand and back to Scottish music - I never realised his influence on Scottish music until I began to learn piano accordion. My teacher gave me loads of music written by Jimmy himself. I never did them justice but did recognise quite a few which I thought were traditional tunes

As an aside, I sometimes sing a fake hunting song called three jolly sportsmen (taking the piss out of huntsmen). The chorus uses hunting calls - "With a ran-tan-tan and a chivy-chivy-chan". I have been known to sing "...and a Jimmy Jimmy Shand" :-)
