G'day again,Murray on Saltspring: From Sydney (Australia) I can't come up with too many local ways to research regional bands in Scotland - although this WWWeb is an astonishing aid to my researches.
What about the direct approach? Ask the man; now he is coming back to Earth after the Knighthood. (It's nice to see a gel that does what her mother tells her to!)
I presume that there is some sort of fan club for The Jimmy Shand Band - or, at least for his son's band, which he still augments on occasion. By God, there might even be a Web Site, run by wise people that know that computers and accordions can still live in the same multiverse!
Regards,
Bob Bolton (who plays concertina, mouthorgan, whistle, bones, lagerphone, tea-chest ['bush'] bass ... even [rarely] guitar and banjo ... but when he really wants power - plays button accordion!)
