Stuart,
Thought Id found it for you on eBay but never realised that a Veleta was a generic name for a waltz style, and the one I found never matched the tune. Ill keep trying.
Never heard of a veleta before. Never knew they made scooters!
EDIT:- There appears to be various sheet music regarding a tune named The Veleta, and I dont really know which one is which. It also appears in The Netherlands as De Veleta
Try this one on amazon and see if it looks like the one youre trying to find:-

Unfortunately I dont know much about Jimmy Shand, and am not familiar with his repertoire.
That same sheet music is also listed twice on eBay. One very rough looking, and the other one a bit pricey.
