Cover art for Carry On Screaming lyrics by London After Midnight

This is easily one of my favorite LAM songs.

To me, it means this: There's this person, and they're just so confining to the singer, and all the singer can do is scream and take the pain. The person takes pleasure in the singer's pain, and are empty inside because the singer's pain is all they have.
