A story that links Barack Obama and Beyonce but the BBC aren't interested.... Why not?

The BBC seem oddly uninterested in the news that Beyonce did not sing live at President Barack Obama's inauguration ceremony yesterday. I wonder why?

The last mention of Beyonce on the BBC news website comes on this page :

'...while singer Beyonce performed the Star Spangled Banner.'

'Performed' - an interesting choice of words by the pro-Obama BBC.
