Eric:
Off tunings and wrong lyrics go back to the '60's with the Stones.
Wrong songs: same deal.
The Stones are not overdubbing live - if you mean they're overdubbing their live recordings, same thing, it goes back to the '60's.
Messed up soundboards? As virtually everyone agrees, they mixed the guitars way up on this tour, and the results are tremendous.
There are too many great fresh things the Stones are doing live now, from blistering, first ever concert renditions of tunes like CYHMK in '02 (complete with awesome solos by Ron Wood and Mick on harp), to resurrecting great live numbers such as She's So Cold and As Tears Go By on the current tour, to their absolutely stunning versions of some classics like Midnight Rambler (performed BETTER than any official live version at times during AB

, Everybody Needs Somebody To Love on the previous tour, etc. etc.
As shattered said, "it does cook and people know it." Go to a show and let the Stones silence your concerns.
