Nancy Lamoureux Wilson is an American musician. She rose to fame alongside her older sister Ann as guitarist and second vocalist in the rock band Heart.

"Magic Man" is a song by the American rock band Heart released as a single off their debut album, Dreamboat Annie. Written and composed by Ann and Nancy Wilson, the song is sung from the viewpoint of a young girl who is being seduced by an older man, much to the chagrin of her mother, who calls and begs the girl to come home. In an interview, Ann Wilson revealed that the "Magic Man" was her then boyfriend, band manager Michael Fisher, and that part of the song was an autobiographical tale of the beginnings of their relationship. Roger Fisher came up with the alternative tuning EADGDG for his guitar part. The album version of "Magic Man" features an over-two-minute instrumental break which consists of a guitar solo and the usage of a Minimoog synthesizer, while the single version of the song edits out most of this break, cutting it down from 5:28 to 3:29.
