You can contact the Yetties directly at their page of mp3 song files regarding Thomas Hardy. I have this info from John at Celtic Ways, who handles the Yetties on mp3, regarding Hardy's manuscripts:
................. The Yetties brought out a double album on Thomas Hardy called the Thomas Hardy Heritage.

The double album is about 60 tracks of music and prose. Most of the music is played with Thomas Hardy's own violin, or the violin of his father's. Thomas Hardy was primarily a folk fiddler. Its how he earned his living and much of what The Yetties do are arrangements from Thomas Hardy's own collection of music and song manuscripts that are still handled by his descendants.

You might have noticed that the only real MP3.com hits the Yetties have had are Dribbles Of Brandy and The Mountaineers - both played on Thomas Hardy's own violin that he made his living with.

The record company that released the double album have gone bust and I now have the rights to release it in the USA. The Yetties have released it under their own label in Europe. ....................
