What song took Stevie 8 takes to get right?

[louielouie2000]

So my little indie classic pop/rock station here in town is always dispensing the best trivia, plays the most forgotten old songs, album tracks, etc. As an example, they LOVE playing the demo version of Gold Dust Woman; they also play Think About Me, Sentimental Lady, and other Mac gems from time to time.

Anyway, my husband was getting out of the car they other day, and my fav DJ was saying "and here's a Fleetwood Mac tune that took Stevie Nicks 8 takes to get right." He didn't wait and listen to what song it was, because he assumed I'd know LOL. Anybody know this random bit of trivia?
