Saturday Night Live begins its 39th season tonight, and if I had to consider every musical performance in the show’s history, I would vote for Devo’s cover of “Satisfaction” on the October 14, 1979 episode as the best of all. Performed just a week after the Rolling Stones was the program’s musical guest, this reimagination did for the head what Michael Jackson’s Motown 25 showstopper later did for the feet: It was moonwalking with the brain. They took the soul and put it into the machine.
