America's oldest continuously-active classical music organization is celebrating its 200th anniversary. It was formed on April 13, 1815 in Boston. "The society announced itself with a concert at the King's Chapel on Christmas Day 1815, when 100 singers -- 90 men and 10 women, with the tenors singing the soprano parts -- and 13 instrumentalists performed the first part of 'The Creation' and arias and choruses from various Handel works."
