Fleetwood Mac singer Stevie Nicks composed this song on a Fender Rhodes piano in about 10 minutes. It was however up to the bands pianist Christine McVie to perform the piano part in the studio. She was less than excited about recording the simplistic part in Nicks played in the demo. As she described it… “just three chords and one note in the left hand” and “boring”. A little reworking of the chord voicings led to this amazing Fleetwood Mac classic.
