Right, I've now completed listening to all of the LND CD, and to be honest...I'm 50/50. (Whilst my deluxe edition is on its way back to Dress Circle, I bought the normal version from Asda for £7

)
Some tunes are just absolutely horrendous and don't fit in with anything. There's a heavy rock song that The Phantom and his son sing, and it's just awful and doesn't fit with anything.
However, the Phantom and Christine's duet is really lovely and I do like it very much. Raoul is just an idiot, I hate his character so nothing to be said about him. He's an alcoholic in this show.
I will say though, and I said this when I heard Ramin Karminloo sing at ALWs 60th last year, I hate his voice as Phantom. Sierra Boggess is a lovely Christine, but Ramin's vocie just doesn't suit Phantom.
ALW has written inside it that 'I haven't used any of the same themse from the original Phantom, except one minor exception, but I will say now before anyone else does, I have used 'The Heart Is Slow To Learn' etc etc and goes on about that...
HOWEVER ANDY!!! You underestimate we 'Phans'. There are at least 6 that I've come across after first hearing, tunes that are used in the first Phantom.
These include 'The Journey to the Cemetery' theme, the original intro to 'The Phantom of the Opera' (not the version eventually used in the show, but the 1985 single,) the little instrumental break from Masquerade, the freak-show music from the film, and a 'Say you'll share with me, one love, one lifetime' theme from 'The Final Lair.'
The tune I was expecting to hear (Masquerade) didn't make it in!! (Unless I've missed it on first hearing,) because in the book this was based on the Music Box Gustave has plays Masquerade, and on the cast recording it plays the bit mentioned from 'The Final Lair.'

Hmmm....
Anyway, I'd go see Phantom of the Opera any day of the week, I've seen it 6 times and would go again and again...From what I can gather, Phantom 2 is just a 'one-trip'!!
