I don't 'recall' such noises in my copy of that recording but honestly, I rarely get all the way to the encore unless it's just playing as background music and I'm not listening that closely.
The only time I regularly get a distortion like sound is when playing Rockband. Despite the praise for Rockband's use of the original masters, in many tracks I'd swear that I have a tweeter problem to the point it's scary. However, because I've never hear it in any other material, I'm convinced it's just in the game. I think it might even be the crowd clapping that they add in causing the problem.
