Stayed up to watch, loved the choreography, liked the tunes, thought she looked and moved OK, couldn't tell if she was lip syncing or not. Problem to me is the singing sounded like the studio, so if that was live I'm impressed. Alternatively, if that was lip syncing then that looked perfect too so I'm impressed at a technical level if somewhat let down.

No one's got near Mr Springsteen's half time show. He's not called the Boss for nothing.
