Does America do The Proms??
I honnestly dont know...but in England, every year there are a number of concerts known as "The Proms" where famous, or beautiful choral or classical music is performed.
The most well known concert is "The Last Night Of The Proms" which is always hosted at The Royal Albert Hall, and is Televised on national terrestrial TV. The last Third of this Concert is ALWAYS the same, and includes all the British Patriotic Classics, Rule Brittania, Land of Hope and Glory, and Jerusalem.
Obviously the Proms end with a rendition of the British National Anthem...but its rather odd.
