Yankee Doodle

Yankee Doodle is an American patriotic song that plays on Enclave Radio. The arrangement used in Fallout 3 was done by Kelly Richmond and can be found on Proud and Spirited (WSR171), which is only available for movie/TV/game licensing from Westar Music.

Background
This tune was originally sung by British soldiers during the Seven Years' War to mock the Americans (who were then called "Yankees").
