The song comes off Stewart's 1984 Camouflage album. The LP peaked at #18 in the U.S., while "Infatuation" hit #6. It is not a terrible song, and is typical of the lightweight, somewhat commercial pop material that Stewart was recording in the 1980s. However, the video is something else.
The music video was directed by Jonathan Kaplan, who is probably best-known for his 1988 film, The Accused. Mostly taking place in an apartment complex (as a homage to Hitchcock's Rear Window), the vid features Stewart as a voyeur infatuated with a mobster's girlfriend (played by Kay Lenz). Character actor Mike Mazurki rounds out the cast as the mobster's enforcer or bodyguard.
Shot primarily in black and white, the storytelling, camera shots, and connection to the song's lyrics made this a truly exceptional video, in your author's opinion. Several scenes really jump out, including the intro in the pool, the goldfish feeding, and the scenes where Stewart dances in front of the oversized picture of the object of his affection. And it has Jeff Beck, who brings his sizzling guitar with him.
Stewart would go on to have a long and successful career in the music business, though he did transition to something of a crooner in the 1990s.
Cool trivia fact: There were two version of the video made. In the one above, the mobster rides off with the girl. In the second version, below, Stewart gets the girl (or maybe it is just in his head).
Cool trivia fact #2: There is a solid interview with actress Kay Lenz at Noblemania.
Lastly, we found a cool making of video with Rod Stewart and Jeff Beck, so of course we had to include that too:
