"Als the solo on Save Me on the WWRY DVD is not synchronize with his hands (watch carefully)"
The reason for that is because originally the films used to film the two concerts that were edited for the concert video had no sound to them. That's why they had that huge digital clock on the right side of the stage (audience's view), to synchronize the film reels to the clock. Even then, sometimes they used the wrong footage in certain places (watch the drums and cymbals during the guitar solo part of WWRY Fast, you'll see what I mean), and sometimes they used footage for a song from one night while the audio was from the other night, or vice versa.
The only thing that was overdubbed on the WWRY film was the audience, because they weren't being very cooperative until the hard rock part of BohRap
