Saw this photo over on When You Awake -- not entirely sure of the time period, but certainly around the mid-70s when Rumours came out.
From Rolling Stone: Rumours, "the sixth-best-selling album of all time owed its success to Fleetwood Mac's willingness to turn private turmoil into gleaming, melodic public art. The band's two romantic couples — bassist John and singer-keyboard player Christine McVie, who were married; guitarist Lindsey Buckingham and vocalist Stevie Nicks, who were not — broke up during the protracted sessions for Rumours. This lent a highly charged, confessional aura to such songs as Buckingham's 'Go Your Own Way,' Nicks' 'Dreams,' Christine's 'Don't Stop' and the group-composed anthem to betrayal, 'The Chain.' The Mac's catchy exposes, produced with California-sunshine polish [and recorded in Sausalito], touched a nerve; Rumours, a landmark Seventies pop album, ruled Billboard's album chart for thirty-one weeks."
