Christine McVie composed the song using a portable Hohner electric piano in a small apartment in Malibu, California, where she and then-husband John McVie (Fleetwood Mac's bassist) resided after completing a concert tour to promote the previous album, Heroes Are Hard to Find. The original rhythm track consisted of just vocals, drums and a Dobro. Other instruments were later added to embellish the song, including McVie's Vox Continental organ. Billboard described McVie's vocal performance as "a completely distinctive voice, with a sexy huskiness that is unique in pop today."
