Some notes from Josh on Slower Than Dirt:
This is a different “Rose Waltz” than any of the ones I could find online when I learned it. I’ve since learned that the more common name for this tune is The Shepherd’s Wife, or Shepherd’s Wife Waltz. I learned it from Sarah Comer, who got it from Stuart Williams, I’m pretty sure, so I should drop him a line and find out if he knows how it picked up the “Rose Waltz” title.
