Another observation: Mick seems ....

While they started 'You Can't Always ..." I noticed that on the back of Micks right hand,
just above the wrist, he seems to have a rather large I dunno, lump / bump / abscess maybe ? Its very notable while his right hand is around his microphone. I watched closely to see if it was just a shadow caused by the lighting but nope, looks like an abscess really.
