"Barretta's Theme (Keep Your Eye on the Sparrow)"
"Theme from "S.W.A.T."" is an instrumental song written by Barry De Vorzon and performed by American funk group Rhythm Heritage, released on their debut album Disco-Fied. It reached number one on the Billboard Hot 100 singles chart in the United States on the chart date of February 28, 1976.
As the title implies, it was the opening theme music for the 1970s American television series S.W.A.T., though it is a noticeably different recording than the actual TV theme version. The theme song was also referenced by characters in the 2003 motion picture of the same name, who mouth the notes during a party to celebrate their successful completion of the training course.
The central refrain sounds remarkably like a one of the repeating themes in the first movement of Dimitri Shostovitch's Symphony No. 5 (1937).
