A year after the Soul Train theme became the first TV theme song to reach #1, another instrumental track repeated the feat. Funk group Rhythm Heritage’s ‘Theme from S.W.A.T.‘ peaked at #1 for a single week in February of 1976.

Though Rhythm Heritage’s version of this track enjoyed the sales success, the cop show used a different recording for its opening titles, one performed by an orchestra led by Barry De Vorzon, who wrote the song. That version sounds more like a TV theme and less like a funk jam, to its detriment.

Like yesterday’s featured artist, Rhythm Heritage never sniffed a Billboard hit again after enjoying the success of this one. TV theme songs, it seems, are ripe territory for one-hit wonders.
