Re recorded in studio??

I can't remember where I read it but I recall sammy saying that he was forced to re record some of this in 5150 studio prior to release?

So it wasn't really recorded live in front of an audience? Anyone have any more info on this?

I have seen a video somewhere of the guys playing won't get fooled again by the who in 5150 studios so that may have been the recording they claim was live??
