I agree. This is where Emperors New Clothes comes in. If anyone else performed like this it would be deemed 'not very good' but it is just 'ignored' as it is unmentionable as you can't say that about Susan. The worst I saw was her attempting to do a duet with Elaine Paige - dear oh dear. I felt for Elaine trying to sustain the duet as Susan was oblivious to rhythm/timing.
I find this a specious comment. I felt Elaine Paige was showing her age, though Elaine sings lovely, Susan's performance was remarkable and assured. I loved the remake with Peter Kay, he did a wonderful job. If you don't like Susan's music, so be it.
How anyone can feel comfortable spreading unsubstantiated rumors like the one that initiated this thread mystifies me.
