I realized 5 years too late that when I bought the Grey Gardens original broadway cast album, amazon sent me the off-broadway cast album instead. Which version is better?
I also listen to the Broadway album more often. Most of the tracks are the same but similar to the Fun Home Broadway cast album they did make a few changes and the updated recording reflects that.
The differences in the score are really pretty significant. Far moreso than the difference between the Fun Home albums. Many whole songs are replaced or cut, with lyrical changes in other numbers.
I did not see either run of the show, but vocally I much prefer Sara Gettelfinger.
Although she did not seem to commit to a "Little Edie" voice I think her voice is so interesting and it's pretty much the only recording with her in a lead role.
And I do prefer that version of the score (again I didn't see the show so I can't vouch for or against the whole iterations of the show).
