If you are thinking of "The Hardy Manuscript" collection of tunes,such as ; Waltz in G ---The Seven Stars---Jacob or Enrico--The Pandene Dance---The Pandon of Tikeli...and other such delights, it is available to look at in Dorchester Museum. And it's NOT by Thomas Hardy, but is, rather, a collection put together by his grandfather !! ( The Hardy family were very musical !). And don't forget too ----the nearby hilltop "Hardy Monument" is nothing to do with Thomas Hardy either; it's a monument to Captain Hardy of HMS Victory fame ( "Kiss me, Hardy " etc. !!) So there !
