Lisa is an unreleased track recorded in Summer 1980 at Prince's North Arm Drive Home Studio in Orono, Minnesota. It was filed for copyright at the Library of Congress on 4 August 1980. It is not known if the track was intended for any particular project, although its distinct synth sound and monotonous, hypnotic feel, probably led to Prince discarding it from any consideration for the Dirty Mind album. An edited version also exists, potentially for inclusion on a single, although this is unverified.
The track is possibly named after band member Lisa Coleman but could also be about another Lisa, including a Minneapolis girl named Lisa LaSalle whom Prince was hanging with at the time. The song contains humorous lyrics about tempting her away from her lover.
The track is unrelated to the 1984 instrumental Lisa (later renamed Yes).
