How Deep Is the Ocean?

"How Deep Is the Ocean?" is a popular song written by Irving Berlin in 1932. The song was developed from an earlier Berlin song "To My Mammy" which was sung by Al Jolson in his film Mammy (1930). In the earlier song, the lyrics include the questions "How deep is the ocean? / How high is the sky?" and this was the genesis of "How Deep Is the Ocean?".
