My Guy is a 1964 hit single by American singer Mary Wells for the Motown label. Written and produced by Smokey Robinson of The Miracles, the song is a woman's rejection of a sexual advance and affirmation of her fidelity to her boyfriend, who is her ideal and with whom she is happy, despite his ordinary physique and looks.

At the session for the "My Guy" backing track, the studio musicians were having issues completing the intro; the musicians had been playing all day and only a half-hour scheduled studio time was left. Trombonist George Bohanon said to keyboardist Earl Van Dyke that the opening measure of "Canadian Sunset" could be perfectly juxtaposed on the intro's chord changes, and Van Dyke, the session bandleader, expediently constructed an intro incorporating the opening of "Canadian Sunset" and also the "left hand notes" from "Canadian Sunset" composer Eddie Heywood's rendition of "Begin the Beguine". Van Dyke would recall: "We were doing anything to get the hell out of that studio. We knew that the producers didn't know nothing 'bout no 'Canadian Sunset' or 'Begin the Beguine'. We figured the song would wind up in the trash can anyway". (wikiwand)
