Susan,
It sounds like Glenn to me. It surely was left in there on purpose.
It was likely one of those things that happened in the moment and he decided to leave it on there. I'm guessing that they really had it cooking so to speak playing wise and the said comment was in reference to that.
I noticed it after a listen or two. I was wondering when it would be brought up.
Oh..I know...I was just being funny. Actually...I was guessing it sounded like Chad saying it...didn't hear an accent.
