"Three Little Words" is a popular song with music by Harry Ruby and the lyrics by Bert Kalmar, published in 1930.
The Rhythm Boys, accompanied by the Duke Ellington orchestra, sang it in the Amos 'n' Andy film Check and Double Check. It also figured prominently in the film of the same name, a biopic of Kalmar and Ruby.
A recording with Sid Philips and his Orchestra Refrain: Johnnie Eager was made in London on September 25, 1950. It was released by EMI on the His Master's Voice label as catalog number BD 6077.
Al Martino used this song in his Las Vegas and touring shows as an encore and band solo signature tune.
In the mid 1970s the Advertising Council used a fully orchestrated instrumental version of the song in a series of PSAs about seat belt safety; the tag line of these spots were "Seat belts: a nice way to say 'I Love You'."
