"Someone to Watch Over Me" is a song composed by George Gershwin with lyrics by Ira Gershwin from the musical Oh, Kay! (1926), where it was introduced by Gertrude Lawrence. Gershwin originally approached the song as an uptempo jazz tune, but his brother Ira suggested that it might work much better as a ballad, and George ultimately agreed. It has been performed by many artists since its debut and is a jazz standard as well as a key work in the Great American Songbook. It is also referenced in the Frank McGuinness play Someone Who'll Watch Over Me.
