"Someone to Watch Over Me" is a 1926 song composed by George Gershwin with lyrics by Ira Gershwin, assisted by Howard Dietz who penned the title. It was written for the musical Oh, Kay! (1926), with the part originally sung on Broadway by English actress Gertrude Lawrence while holding a rag doll in a sentimental solo scene. The musical ran for more than 200 performances in New York and then saw equivalent acclaim in London in 1927, all with the song as its centerpiece. Lawrence released the song as a medium-tempo single which rose to #2 on the charts in 1927.
