Mid-1981 was the first great period of prolificacy for Prince. In astonishingly little time, he completed work on his own fourth album, a full-length debut for protégés the Time, and several other assorted odds and ends, including a handful of songs for the Hookers (“Drive Me Wild,” “Make-Up,” “Wet Dream,” “Gym Class,” “I Need a Man,” “Jealous Girl,” “Mink Kitty Cat,” and “Pizza”), as well as other tracks with tantalizing titles like “Delivery Boy,” “Friction,” “Heart Attack,” “Hump You,” “Poppa Grooves,” “The Rain and You,” and “See U Dead.” One of those odds and ends would even end up on the album: the taut funk track “Let’s Work.”
According to legend, “Let’s Work” began life as “Let’s Rock”: Prince’s version of a ’60s-style dance craze song, like “The Twist” or “The Loco-Motion.” The song, inspired by a dance Prince had seen in Minneapolis clubs called “the Rock,” had been kicking around as early as 1979; its title appears in one of Prince’s notebooks in what appears to be an early, handwritten tracklist for the Prince album, alongside “I Wanna Be Your Lover,” “Bambi,” “Why You Wanna Treat Me So Bad?”, “When We’re Dancing Close and Slow,” “With You,” “Still Waiting,” “It’s Gonna Be Lonely,” “Sexy Dancer,” and “Darling Marie.” When it didn’t make it onto the album, Prince allegedly tried to release it as a non-LP single; but Warner didn’t bite, a minor setback that, in retrospect, foreshadowed more serious conflicts with the label to come.
