"Nobody Knows You When You're Down and Out" is a blues standard written by pianist Jimmie Cox in 1923 and originally performed in a Vaudeville-blues style. The lyrics in the popular 1929 recording by Bessie Smith are told from the point of view of somebody who was once wealthy during the Prohibition era and reflect on the fleeting nature of material wealth and the friendships that come and go with it. Since her 1929 recording, the song has been interpreted by numerous musicians in a variety of styles.
