THE OLD GUARD FIFE & DRUM CORPS INSTRUMENTAL ENSEMBLE
8TH ANNUAL MUSICAL PRELUDE TO NATIONAL CHERRY BLOSSOM FESTIVAL
SOUTHWEST WATERFRONT WASHINGTON, DC

If their calendar is correct, they are only performing twice this year, (the only other performance was today in the St. Patrick's Day parade in NYC) so this will be last chance to see them until 2012.

If you like fife and drum corps music, you can download their performances for free:

(Yes, I know they wear Rev. War uniforms, but some of the tunes they play--Downfall of Paris, Paddy on a Handcar, Yankee Doodle, Jefferson and Liberty, etc. are also part of the Civil War era repertoire. Besides, they are the only active fife and drum corps in the U.S. military and they are really good. They can't help it if their commander chose uniforms from the wrong era. )
