I've always been of the opinion that a singer's voice doesn't need to be as good as, say Adelle or whomever you class as having an amazing singing voice. Lennon & McCartney's weren't brilliant IMO, but the rest of what they did meant it didn't matter.

Same with Bon Jovi, the overall package of what you get doesn't mean that his deteriorated voice has ended his career. Sure, it hampers types of songs he can sing in the studio and live, but it could be a lot worse, take what Meat Loaf sounds like now.

I liked the Live CD, it added that rawness (or rather over produced sound) to the songs that I'd like to hear on studio versions.
