"When Love is New" come a 2000 soundtrack from the film Songcatcher. The film was a musicologist who goes to Appalachia to study / record the songs of the people.
A lot of Appalachian derives from Scottish music, but that's another post for another time.
The soundtrack is quite good - with some familiar artists, some sticking strictly to the roots music, some a little less so, but the spirit is there.
One of the songs is a duet from a film cast member, Emmy Rossum and Parton herself (though she is not in the movie).
The song story is good - as the nature of the music is storytelling - the harmonies are off the chart. I've barely seen Rossum since (and never before this) and never heard her sing save or "When Love is New".
While I believe she is singing in character - as I don't think she is from Appalachia - it goes to her credibility for her, or her people, to research the role.
.....and Dolly is a storyteller, so this is right up her alley.
