Susannah's Pajamas is the seventh track on The Family's first and only album The Family, and, two months after the album's release, it was included as the b-side of High Fashion, the album's second and final single. Susannah's Pajamas was written by Prince and Eric Leeds, but credited only to Eric Leeds.
Basic tracking (under the track's original title, Mazarati), took place on 22 June 1984 at the Flying Cloud Drive Warehouse in Eden Prairie, MN, USA (five days before tracking of High Fashion, Mutiny and Desire). The track was originally intended for Mazarati's album Mazarati, but when it was used instead for The Family, Prince changed the title. A track titled BMW appears on an undated early work-in-progress configuration of the album, and this is believed to be the same track renamed after a different make of car. It was then renamed after Susannah Melvoin. On an acetate made of the LP, the content of which was not different from what was eventually released, the song was titled "Susannah’s Clothes".
