The song, which is written in the key of E-flat minor, is told from the point of view of a boy who has been taken in for questioning about the murder of a girl named Jenny.
After explaining the incident from his perspective, the boy (voiced by Flowers) says, "There ain't no motive for this crime, Jenny was a friend of mine."
The song was inspired by the videotaped confession to police that Robert Chambers made the morning after the death of Jennifer Levin.
"[8] Adrian Begrand, writing for PopMatters, called the song a "spot-on, wonderfully shameless Cure imitation", and praised Flowers for his "charmingly overwrought depiction of a lover's spat “on a promenade in the rain.”"[9] In her "Ask Hadley" column in The Guardian, Hadley Freeman noted the similarity of the song's storyline to that of Richard Marx's 1991 hit single "Hazard" and accused the Killers of "blatantly rip[ping] off" the latter.
[11] The Times wildly praised the song, saying "Jenny Was a Friend of Mine rejoices in a helicopter sound effect last heard when Oasis were going through their pompous phase, a bassline that New Order's Peter Hook would be proud of and a stupidly catchy melody that would fit primetime Duran Duran."
