"Lafayette" is an old-time breakdown in D Major. The parts are played AB.
The melody was popularized on the Grand Ole Opry by fiddler Kirk McGee (1899-1983).
Jon Pankake (who wrote the liner notes for Milk 'em in the Evening Blues) interviewed McGee in 1965, and was told that "Lafayette" was "an old Civil War tune," although McGee did not mention a source for his version. McGee recorded the tune playing the fiddle, backed by Fiddlin' Arthur Smith on 5-string banjo and it was popular for many years as a dance tune on the Grand Old Opry.
It was printed in Silberberg's Tunes I Learned at Tractor Tavern (2002) and Lamancusa's The Gettysburg Collection of Old Time Fiddle Tunes (2021).
It was recorded by Kirk McGee (fiddle) & Arthur Smith (banjo) on Milk 'em in the Evening Blues (1968) and Jim Wood & John Hartford on The Bullies Have all Gone to Rest (1998).
