"Bang Bang (My Baby Shot Me Down)" (1981)
First sung by his then-wife Cher in 1966, Sonny Bono's tale of a clearly dysfunctional relationship made like a folk-rock novelty song. (On the plus side, it set Cher on the story-song course that led to more enduring triumphs like "Gypsies, Tramps and Thieves" and "Half-Breed.") Slowed down and turned into a piece of theater, Sinatra's version is dark and melancholic — as much a dramatic reading as a mere remake. Sinatra's last stab at rock (his next — and final — solo studio album, L.A. Is My Lady, returned him to the land of Cole Porter and Harold Arlen) but a nice way to go out.
