I agree very much that his voice is weakest this tour than on previous tours...so not trying to apologise....but I do think opera singing is actually very similar....very high and powerful notes that you need to hit 100% from the diaphragm. Not trying to be a dick - but I think things like the extended scream he used to do in LALD circa 2002 are actually using the same kind of body responce you'd do in opera to hit the massive notes in a song like nesindorma.

You can't pull off AFD or opera without breathing properly and I don't think being fat in and of itself should inhibit that.....

Unless it comes back to the movement/entertainment side of it..like the dancing and walking around is mildly winding him leaving him breathless for hitting the notes....but I know bigger guys who can hit epic powerful stuff in a variety of genres including metal.

It's curious though that he's used oxygen for years, makes me wonder if the years of smoking or something else is actually a factor as well, I don't deny his voice has issues at the moment, I'm just saying I wouldn't rush to judgment that it's about his diet.
