the rumor i'd heard (way back-in-the-day & popping up at times through the years) was that either part or all of the vocals off WOA album (and, thusly/probably, the rockshow movie) were redubbed AT THAT TIME...i never read/heard/saw anything to either confirm or deny it...
of course...i've heard that very same idea about just about every live album...ever...so who knows: it can't be true for nearly all of them, can it ?
either way, i would suspect that is the rumor to which has been alluded to by friend JQ
...course...i'm not totally sold on the supposed autotuning on NYC...after all, why ???
he has so many specious and faltering vocals out there, including a few off recent studio albums...why do it ?
lift up your head...and remember what your life is !
