James Brown, "Get Up (I Feel Like Being a) Sex Machine" (1970)
The Seventies was quite possibly the Western world's sexiest decade. The post-birth control and pre-AIDS window of opportunity saw the Sixties' utopian fantasies elaborated into hitherto unimagined new possibilities. James Brown got in on the libidinous free-for-all early with a landmark single that promoted his, er, endurance and vitality with a simple euphoric groove. His young, hungry and economical new band, the J.B.'s, featured brothers Bootsy and Catfish Collins on bass and guitar, respectively, and Jabo Starks on drums. Bobby Byrd plays hype man in this magically off-the-cuff rearrangement of the horn-heavy James Brown Orchestra's "Give It Up or Turnit a Loose."
