The fifth and last section of Aaron Copland’s ballet, Rodeo, is written as either Hoedown or Hoe-Down. Details on the piece are at Wikipedia.
Other well known Copland compositions are Appalachian Spring and Billy the Kid. This version of Fanfare for the Common Man is performed by The New Frankfurt Philharmonic and Emerson, Lake and Palmer. ELP recorded the piece in the 1970s. It appears that this clip is far more recent.
Here is more on Copland at the Copland House website. The house, where Copland lived for the last 30 years of his life, is in Cortlandt Manor, N.Y, which is about an hour from New York City.
