Prances? He sits at a piano and sings. Are you sure you're not mixing him up with Prince at the halftime show? He prances.
Whoever did it was prancing around. I'm not an afficionado of pop music and wouldn't know Billy Joel from Adam. I asked my son who it was that was butchering the Anthem and he told me it was Billy Joel. And the guy was prancing, whoever he was. Or maybe he was doing the singing and they got a real faggot to do the prancing. Either way, I wasn't impressed, either with the singing or the prancing. Francis Scott Key was probably turning in his grave.
