Christine McVie wrote this about leaving the past behind. She and John McVie (Fleetwood Mac's bass player) were splitting up, which inspired the lyrics. This caused some awkward moments, since John had to play a song written about him. Lindsey Buckingham and Stevie Nicks were also going through a breakup and writing songs about each other ("Go Your Own Way
"), and Mick Fleetwood was going through a divorce. All the tension in the studio didn't seem to hurt - Rumours
is one of the best-selling albums of all time.
