Jam on Gerry’s Rock, alternatively written as Jam on Jerry's Rock, is a folk song. It has been recorded by the Wisconsin Folk Song Recording Project, The Limeliters, Pete Seeger, and the Mallett Brothers. The song is about a young foreman warning his colleagues as he is about to break up a log jam on a river. After the surge he is eventually found bruised, bloodied, and dead downstream, with the song serving as tribute.
There has been research and speculation on the song's origins.[1] [2] There are various title variations and iterations of the song.[3] It is generally associated with Maine.[4]
