I agree with that. Especially on this level. I think it would actually be embarrassing to try to blame it on something like this.

You would also think at high profile performances that require flawless execution for the sake of your reputation, you would play the whole thing safe: look over everyone's heads, even at fixed points of the wall or something else non-descript behind them, and to just really not let a single thing break your concentration...

I am not a professional singer and I am well aware of this advice, and I have used it when speaking before classrooms and such before, and always found it worked pretty flawlessly... No idea how you are a professional singer performing at the BAFTAs and it's like, "Yeah, I'm really nervous, how about I start looking into the faces of famous people while performing? That'll keep me on point..!"
