Cover art for Johnny and Mary (Robert Palmer cover)  lyrics by Placebo

To me, it seems like Johnny is a musician or an artist or a writier of sorts, but one whose ego makes him think he's better than he is.

"Mary counts walls, knows he tires easily" To me, I think that's about their sex life. She fakes everything but is never satisfied because he doesn't have the stamina.
