Does James Actually Play His Guitar At Metallica Shows?

Hetfield

So everyone is talking about James Hetfield falling in a trap door on stage in Amsterdam.  He's ok.  The show went on.  I noticed something in the video though...when James falls into the hole there is absolutely no change in the audio!!!  You would think that slamming a guitar into a hole in the stage would make some sort of sound right?  Was he actually playing?   Watch for yourself and decide.
