"Deep Purple" is a song and the biggest hit written by pianist Peter DeRose, who broadcast between 1923 and 1939 with May Singhi as "The Sweethearts of the Air" on the NBC radio network.
[6] This version of the song is notable for its second half, in which April Stevens speaks the lyrics in a low and sweet voice while Nino Tempo sings.
The Tempo/Stevens version was intended as the B-side of a song called "I've Been Carrying a Torch for You So Long That It Burned a Great Big Hole in My Heart".
Another brother-and-sister team, Donny and Marie Osmond, revived "Deep Purple" with a note-for-note cover version of Tempo and Stevens's recording in 1975[11] and took it into the Top 20 on the U.S. and Canadian pop charts.
It peaked at number 14 in March 1976[12] on the Billboard Hot 100, with Marie Osmond speaking the lyrics as Stevens had done in the version with Tempo.
