It was creeping up behind everything else. It occurred to us that, because of that we should make it the single, which we did. It sort of crept up and was being played a hell of a lot. When you make an album, you say, ‘That, that and that will make good singles’ in order of preference. As Mick Fleetwood said, not long after the single was initially released, “As a track on the album, it was not considered. Like the band’s evolution, this was another organic decision. The biggest single release off the album was Over My Head although it wasn’t so much as released as ‘pulled’. Hence, although the LP took the band in a completely new direction, the new direction was expected and welcomed. The rhythm section remained and Fleetwood was still the captain of the ship, just not the creative force. With his leaving and the introduction of Buckingham and Nicks, the style changed to soft rock. With Peter Green, the most dominant presence in its early days, that direction was the blues and hard blues it was too. As Fleetwood said in the 70s, the band is merely a rhythm section awaiting writers to take it into varying directions.
Neither, though, has a real influence on its music. In fact, Fleetwood Mac’s very name is based on its rhythm section: Mick Fleetwood and John McVie. Most bands are, for good or ill, stamped by the style of their lead singer with very few exceptions (King Crimson and Robert Fripp being one of those). The above needs a bit of explanation, because Fleetwood Mac belongs to an exclusive club.
