Eggplant is an unreleased duet song between Wendy and Prince, recorded on 8 July 1986 at Prince's Galpin Blvd Home Studio (the day after he recorded Train and the day before he recorded It Ain't Over 'Til The Fat Lady Sings).
Inspiration for this song came from Susannah and Wendy Melvoin, as Prince overheard their conversation about vain girls
who constantly flip their hair while having a conversation with someone. The song makes an analogy between a shallow girl and an eggplant, presumably the opposite of an egghead (an intellectual).
While the sessions concentrated on material for the aborted musical possibly known as Dream Factory, as well as the aborted Dream Factory album, it is unknown if this song was intended for these or any other project.
