Sorry to hear this sad news. Bobby was always one of the true gentlemen of the Scottish folk scene, and a fine performer. Point of information. There were 2 Davy Tulloch's. The DT who was a plumber in Ayr was fiddler Davy Tulloch from Shetland. He made an excellent recording of Shetland music with Tom Anderson, Aly Bain & Trevor Hunter, but never had any thing to do with 5 Hand Reel. He too, sadly died at an early age a few years ago.
