amen
I think you said it correctly. After the TD tour he did his own thing, not much of the BJ stuff, started smoking (verry bad...). He was a bit rusty at the beginning of the crush tour, and yes the own tour was much better.(vocaly)
But after seeing the webcast (sb) i have to say his voice is perfect. No he can't get the high notes in loap, but he.. aren't they a bit extra high for a guy
The webcast showed to me Jon can still sing verry well, and quite easely.
Sometimes the live performances are a bit lower (in key) but i think every band is doing that (??)
