Hi, Stella -
After Sandy and Caroline Paton died, Folk-Legacy Records was taken over by Smithsonian Folkways. Folkways has Sharon Mountain Harmony available as a digital download or as a "Custom CD." There were some vinyl records left over for a while, but they were all disposed of when the family sold the house on Sharon Mountain. I doubt that you will be able to find a vinyl record in good condition, but you never know. I didn't find anything currently available on eBay.
