Don't think it's available any more....
... and I'd imagine this isn't either* - a double CD called Scottish Traditional Tales - Scottish Tradition 17 on Greentrax CDTRAX 9017D (2000).
Recorded by various people from the School of Scottish Studies, it is a fabulous collection of some of the finest story tellers in Scotland. Mainly travellers, though there are some Shetlanders, the majority are told by that close knit group of families. Some of the tellers are more widely known because of their connection with the folk revival:- Betsy Whyte, Jeannie Robertson, Stanley Robertson, but you can also hear that superb story-telling style of two of Alex Stewart's siblings; Andrew Stewart (who emigrated to Canada about 1960) and Bella Higgins


* I'm wrong. Just checked and it is available from the Music Scotland website
