The stage version that is released is actually wonderful. Everything is directly from the movie with the exception of Lina's song "What's Wrong With Me?" which is beyond fabulous. The Broadway version was quite flawed in using Twyla as the director/choreographer and not sticking very closely to the book. The London production with Tommy Steele was even worse. Had the "regional" version been on Broadway it would have faired very well I believe. Paper Mill has a recording out with the uber fabulous and dear Michael Gruber as Don. If you come across it grab it! I did a production of it in 1995 with Dirk Lumbard who was phenominal as well.
"For me, THEATRE is an anticipation, an artistic rush, an emotional banquet, a jubilant appreciation, and an exit hopeful of clearer thought and better worlds."
