by William RuhlmannFleetwood Mac's first album made after the departure of Danny Kirwan features the additions of guitarist Bob Weston and singer Dave Walker. By now Bob Welch and Christine McVie were the dominant forces in the band, and all traces of blues-rock were gone, replaced by Welch's hypnotic melodies and McVie's romantic sentiments married to up-tempo pop tunes. This album gave Fleetwood Mac its best U.S. chart showing yet, but the wonder is that this phase in the band's career wasn't even more popular.
