"Where Did You Get That Hat?" is a comic song which was composed and first performed by Joseph J. Sullivan at Miner's Eighth Avenue Theatre in 1888. It was a great success and has since been performed by many others including J. C. Heffron, Stanley Holloway, Al Simmons and Dave Barnes. The song is now also a very popular piece performed for musical theatre exams (grades 4 to 8) and music hall concerts.
Bing Crosby included the song in a medley on his album 101 Gang Songs (1961).
A broadside ballad in the Bodleian library indicates that this song was written by James Ralmaz (rather than Joseph Sullivan) and performed by J. C. Heffron.
