"Beware My Love" is a song credited to Paul and Linda McCartney that was first released on the Wings 1976 album Wings at the Speed of Sound. It was also used as the B-side of the single that included "Let 'Em In". A live version recorded on June 7, 1976, in Denver, Colorado, was included on the Wings' album Wings Over America and another live version from three days later in Seattle, Washington, was shown in the concert film Rockshow. An excerpt from the Rockshow performance was also included in the documentary Wings Over the World.

Like a number of successful Paul McCartney songs, "Beware My Love" is made of several disparate elements. The song begins with a brief harmonium melody followed by a repeated acoustic guitar figure. (The song's album version has the previous song, "She's My Baby", fading out into the harmonium intro; "Beware"'s single version fades in as the harmonium part fades out into the acoustic guitar riff.) Linda McCartney sings the intro and outro movements, with her voice multi-tracked, effectively singing on behalf of Paul McCartney—who sings the lead vocal in the main song. Over the course of the song, Paul McCartney's singing, as well as the music, intensifies. In the main verses, the singer warns the woman he loves to beware because he does not believe that the other man she is seeing is right for her. In the bridges, he tells the woman that although he must leave now, "I'll leave my message in my song." (Author Robert Rodriguez finds this line ironic, since he believes the song apparently has no message. Authors Chip Madinger and Mark Easter assert that the verses and chorus don't seem to have much to do with each other.)
