Cingular Commercial Music: "A Fifth of Beethoven"

The track featured in the Cingular Wireless commercial (showing a guy in his car calling a girl at her house) is "A Fifth of Beethoven" by Walter Murphy and the Big Apple Band (1976).

It is a disco adaptation of the first movement of Ludwig van Beethoven's Symphony No. 5 in C minor. The song topped the Billboard Hot 100 and became an iconic 1970s dance-floor staple, later featured in Saturday Night Fever.
