In February 1977, Fleetwood Mac released an album written in the middle of the breakups it describes, and the songs came out polished enough to hide the bruises until the second listen.
A toy-bright synthesiser states a melody you could whistle in a playground, and Andy McCluskey starts singing the name of an aeroplane as if the name were a girl's, which, terribly, it was.
A piano states a small, adult figure, no drum yet, and Annie Lennox's voice enters as if she had been sitting with the same sentence all night and had finally decided to say it aloud.
