It is definitely the most complete and sung in English, but the orchestrations are awful and some of the voices are my least favorite of all the Chess recordings (Freddy in particular). I'm also not as fond of the ending with Florence's reprise of Anthem. I think I would have to see that to see if it works. My favorite recordings are the original concept and the concert recordings. The Swedish one is pretty good, too (if you don't mind listening in Swedish) and there is also a very interesting Region 2 DVD of the Swedish production.
Given the international popularity of the score, a full-scale revival is certainly due (not a one-night concert or a concert version). Since Roundabout seems to be successful at revivals, perhaps they could give it a go.
