"Pig in a Pen", also known as "Pig in the Pen" or "Pig at Home in a Pen" is an old-time and Bluegrass breakdown & song. A popular piece in bluegrass tradition, it started as an old-time piece. Tennessee’s Fiddlin’ Arthur Smith claimed to have composed it and did play it frequently on the radio, but some believe some of the verses predate Smith. The chorus is very similar to "Shady Grove". It was first recorded (as "Pig at Home in the Pen") in February, 1937, in Charlotte, North Carolina, by Fiddlin’ Arthur Smith accompanied by Alton & Rabon Delmore (recording as "The Arthur Smith Trio"). It was also recorded by The Camp Creek Boys, Earnest East & the Pine Ridge Boys, Spud Gravely [1960ca] (Pig in a Pen), Smiley Hobbs on American Banjo - Tunes and Songs in Scruggs Style (Pig in a Pen), Old and in the Way (with Jerry Garcia), George Pegram, Bruce Molsky and a number of Bluegrass bands. It was printed in Ford's Traditional Music in America (1940/1965), Phillips' Traditional American Fiddle Tunes (1994), Brody's Banjo Picker's Fakebook (1985), Brody's Fiddler’s Fakebook (1983) and Thede's The Fiddle Book (1967).
