"Let a Smile Be Your Umbrella" is a popular song.
The music was written by Sammy Fain, the lyrics by Irving Kahal and Francis Wheeler. The song was published in 1927 and was the first collaboration between the Fain / Kahal team. Successful early recordings were made by Roger Wolfe Kahn (vocal by Franklyn Baur) and by Sam Lanin (vocal by Irving Kaufman), and these both reached the charts of the day in 1928.[1]
