The original cast (at least the leads plus Jason Alexander) in various interviews have stated that they wish the original version could be made available for performance. Historians like Ken Mandlebaum and respected others who saw the original production.
Don't get me wrong, I love the current revival, which works beautifully probably because the 3 leads are so incredible and the direction works. I just wish the original version could also become licensed so that audiences could see it. Sondheim's score, of course, (all the versions) is beyond reproach.
