It's been frustrating for the writers, which I see from my removed vantage point. There were rights questions that lasted two weeks, and were resolved over a year and a half ago (Summer 2013). They had recorded it three times at Dixon Place, and they were very clear from the beginning that the process would be taking what BD and the mixers were happiest with from all three of the versions of the complete show. I'd imagine that with songs, just figuring out which came out best is an easy process for highly-skilled listeners - but with all of the book becoming subject to almost section-by-section choosing between three versions, I gather it got to be daunting. And it's been evry clear that BD was not working on it AT ALL while he had any acting or directing projects, and also while he was in a very long process of moving, which he would write about very openly in his infrequent Kickstarter updates, to the annoyance of the donors.
And then suddenly, two and a half years have gone by.
Meanwhile, though, the "Lady Day" show which was also a complete one-person show, took a matter of months to get out, so go know.
That's just my view, not Skip's.
