Spread a Little Happiness is a song by English musical comedy composer Vivian Ellis from his 1929 musical Mr. Cinders. Ellis was suffering from a fever of 103 °F (39 °C) when he wrote the song. In the original production it was sung by Bobby Howes as Jim, but Binnie Hale was the singer on the 78 RPM record that was released. English musician Sting covered the song for the soundtrack of the film Brimstone and Treacle. In 1982 it reached #16 on the UK Pop chart. The song was used as the theme tune for a BBC Radio 4 comedy series of the same title.

Great song.
Check out the (rare) official music video from Brimstone and Treacle where Sting does a great soft-shoe – very funny indeed (as opposed to the film):
