Beyonce open and closed her mouth perfectly

Everyone agreed - and by "everyone" I mean "people I follow on Twitter who expressed an opinion" - that Beyonce nailed it at the Obama inauguration.

Now it turns out she got some help being note-perfect when you've actually already done the song and were just miming.

Does it matter? Not really, in the sense that Obama was only miming the inauguration anyway - the actual swearing had been done the day before, and if Barack was just opening and closing his mouth for a performance he'd done earlier.

On the other hand: what was all that 'pulling the earpiece out' business? If she'd been singing live, that would have been a brilliant moment - "Beyonce doesn't need the monitors".

Instead, it turns out to have been a bit of empty theatre.

So Beyonce didn't nail it. She was just very good at using a shortcut. She No More Nailed it.
