I have been watching a few live Jovi performances on Youtube lately...mostly from Tokyo earlier this year, and its sometimes unbearable watching Jon struggle to sing.

In particular In These Arms where he cant reach the high notes and my blood pressure seems to rise as im watching him struggle on through the song(s)!

WHY?
Is this because he's getting old?
Or because he smokes (does he or not?)
Is it because its live?
Is it because his voice isnt/wasnt in shape?
Or perhaps he was singing in a higher pitch??

I dont know, but it sure doesnt sound the same as on the records.
