The most recent references about "Love Never Dies" (that I've seen) are from ALW being interviewed in Cardiff recently:
http://www.walesonline.co.uk/showbiz-and-lifestyle/2009/08/01/andrew-lloyd-webber-i-m-a-quality-control-freak-91466-24280490/ He's gone back to only hinting at Ramin and Sierra, but they surely have effectively been confirmed already. It was quoted from ALW's mouth, even if not officially announced. And I wouldn't be too surprised if Kerry Ellis gets Meg on stage in London either. Whether she would get to open on Broadway as well, along with Ramin and Sierra, is very much more doubtful.
Baz Bamigboye of the British press has certainly been given privileged access, and although he said that he didn't think ALW still had it in him, he thinks the score is amazing and the best thing ALW's done. There has to be consciousness of the need for a bit of a pinch of salt, though, when he has clearly been given given access to effect (It was Baz who confirmed Ramin and Sierra). But he still didn't "need" to be as complimentary as he has been. I haven't seen the Michael Riedel comments though. It sounds like he was given privileged access too. Is there a link anywhere?
