I saw the show last weekend, and I REALLY enjoyed it, so the cast recording brings back joyous memories for me (although I saw Margaret Preece as the Mother Abbess, and listening to Lesley Garrett on the CD, I am very glad to have seen Ms Preece - her voice is the first operatic/soprano type ever to have made me cry).
I might be wrong, but this recording might be the first one to have recorded a stage version of some of the songs from the film, because I read that ALW incorporated some of the film score into his new production.
To top it all off, you can hear Lauren Ward (who played Violet in original production, and is on the recording of that show). I love her light and distinctive voice, and she is EXCELLENT as the Baroness. I met her at the stage door (I must have been one of the first people to have asked for her autograph after that show, most people are there to see Connie - she was REALLY nice).
I'd say get it, because it features lovely Connnie, some new material and Lauren Ward, all in a very well-produced recording.
