"A Man Has Dreams" is a song from Walt Disney's film Mary Poppins, written by Richard M. Sherman and Robert B. Sherman. The song melody is a slowed down version of "The Life I Lead" which serves as Banks' leitmotif as he was fired. In both the motion picture and the stage musical, the song is performed as a conversational duet between Bert, the chimney sweep (Dick Van Dyke) and George Banks (David Tomlinson).
