I really think you're wrong here because his range was at it's lowest on the HAND tour and he had clearly worked extremely hard by 2008 to get some of it back. His Hallelujah long and high notes at the end got progressively stronger and longer from 2007-2010 and I know that for a fact because i've made a sad point of listening to every video and boot I can find of them. I think it's pretty clear he's worked very hard to get that range back and when you see him straining the **** to sing Amen, he's using every bit of technique and every fibre in his body to hit that shit and it ain't easy.
