"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.
The song was the opening theme music for the 1970s American television series S.W.A.T., though it is a different recording from the actual TV theme version, which was not performed by Rhythm Heritage, but by Barry De Vorzon's own orchestra with arrangement by Dominik Hauser. 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. De Vorzon's original was eventually released on the LP Nadia's Theme on Arista records.
It remains one of a few TV themes to top the Billboard Hot 100, a list that includes "Welcome Back" by John Sebastian, "Miami Vice Theme" by Jan Hammer and "How Do You Talk to an Angel" by Jamie Walters & The Heights.
