Lindsey Buckingham originally gave Christine McVie the chords for this tune. The songstress then penned the words for this dreamy reverie about yearning. She explained to Uncut:
"He had already written the chords on guitar, and I came up with the words and the melodies. It's a hooky kind of song and I wrote it about when I was in Africa on a desert island. As usual, it's a love song.
I have notebooks for love lyrics that don't end up going anywhere. Sometimes I jot down lines that somebody might have said and I think, oh, that's interesting, I wouldn't have put it that way. When I do fancy getting to the piano, I take those notebooks with me. If I write a chord change or a rhythm, I'll see if I've got lyrics that go with it. I knit bits together."
