That album is one of my true joys.
It's been a while since I read the script, but I wouldn't say it was abysmal.
It's one of those stories that one person would say that nothing happens in it (All they do is go and sit in a tree) and another person would say everything happen in it (Dolly steps out of her sister's shadow and the sister realizes how important Dolly is to her and the nephew becomes a man...)
Though "Grass Harp" falls closer to the "nothing happens in it" category.
Interestingly enough, the "straight" play written by Truman Capote himself flopped in that same theater twenty years earlier.
You should, of course, consult Ken Mandelbaum's "Not Since Carrie" and Ethan Mordden's "One More Kiss" to read up on the show.
