I think these lyrics, from the audio clip of "When All the Sunshine's Gone" on the production's website, can answer the question of whether or not the show is worth seeing:
Beauty is a thought that's overrated
Where someone needs to wear a jewel to feel they have some worth
But if the jewels are tossed away or buried
Does that make them less upon this earth?
Look at me, a man who shepherds sheep
I love to chase the sheep about and leave them out to roam
And though at night my clothes smell like the pasture
Does that mean I should be all alone?
Someday when all the sunshine's gone
Someday when everything around us is covered in a mist
We'll start to see ourselves the way we're supposed to
Where seeing is replaced by how we're kissed
Someday when all the sunshine's gone
Someday when everyone is accepted as who they really are
Our coats won't be a care
The smells up in the air we'll all ignore
When what's inside is what we'll all adore
