perceptions aren't 'right' or 'wrong', they're just that; perceptions. That's why I said, "To me, it looks like...". You don't have to agree. He's not going to start shouting at the band in the middle of the set, is he? That said, most fans who have seen Moz live a few times can tell a 'relaxed' Moz from an off-kilter, out-of-sorts Moz and from that clip, I think he looks uncomfortable and distracted; he fiddles with his earpiece as soon as he comes in as though something is wrong, he looks back blankly at the band between 2.37-2.40, there are times when he's not focusing on the audience and he does not seem his normal self. Put that alongside the fact that Little Barrie was a stand-in and was making a shitshow of one of his best songs at the same time and I think it's a reasonable conclusion to come to. I have seen Morrissey grimacing at flubbed notes and rolling his eyes at various band f***-ups over the years; he's not an idiot who is just oblivious to whatever else is going on.
Trying to engage with you on any topic is like arguing with a kid - you just say "no, no, no, you're wrong, shut up" and revert to your own reality instead.
