Recorded in 1935, Gallis Pole is both a documentary of the southern prison experience, and a deadly guitar piece. Led Zepplin was inspired to do this song, after Jimmy Page heard a recording of Fred Gerlach play it on the 12-string guitar in the same way that Leadbelly played it. Led Zepplin changed the lyrics, some and the poetry and intent some, but still made mention of the friends who did not bring any silver or gold to save him from the hangman.

Recorded in 1937 in Chicago, Robert Plant used the lyrics as a basis for the song Custard Pie, with lyrics from Sleepy John Estes' Drop Down Daddy.

Jimmy Page once told fellow British musician/author Ian Whitcomb during an interview: "Valens was my first guitar hero and I played that bridge to 'La Bamba' a thousand times."

On July 28, 1978, Led Zeppelin and their record company, Swan Song Records, settled amicably out of court for a reported $130,000 plus future royalties with the stipulation that the settlement's incriminating terms be kept confidential. This song was released in 1959 in Ritchie Valens' self-titled album.
