Cover art for Candy lyrics by Martin Sexton

Candy is a prostitute and her "John" kind of sticks around after to try to get to know the real her...realizing that he sort of loves/pities her.

Some think that this song is also a reference to a drug addiction, "Candy" referring to the guy's drug of choice. (Well, that's my Mom's theory... the first explanation makes more sense to me though.)
