I saw it when Colm Wilkinson was in it too, he actually plays the Bishop in the film.
I thought it was amazing, I agree that Russell Crowe's singing wasn't great but it didn't take anything away from the film itself. Even my hubby, who took me for my birthday, agreed that it was very impressive and he really enjoyed it - he normally hates musicals with a passion so I was quite pleased
The audience also burst into applause at the end which felt really weird!
If you've seen the film and enjoyed it, you MUST go see the stage show - the whole atmosphere is amazing.
