3. Stevie Nicks and Don Henley, "Leather and Lace"
They've never talked much about it, but Don Henley and Stevie Nicks dated for a couple of years in the 1970s. They remained friends even after the breakup, and when Nicks cut her debut solo LP in 1981, Henley agreed to duet with her on "Leather and Lace," a track she originally wrote for Waylon Jennings and Jessi Colter. The country pair named their 1981 album Leather and Lace, but inexplicably cut the song from their disc. It was their loss since Henley and Nicks brought it to Number Six on the Hot 100, proving they didn't need the Eagles or Fleetwood Mac to land songs on the radio.
