Thanks for the link. Often missed: the anthem at baseball games was originally sung by the crowd, spontaneously while a brass band played on the field.

This seems a lot more fun to me than the current (awkward) practice of standing there trying to look more serious than the guy next to you, hand over heart, while some ostentatious diva who lost the last Eurovision contest belts out yet another over-dramatized and over-personalized performance.

The current incarnation of this tradition needs to die for aesthetic reasons, if not political ones.
