[Intro – both, softly laughing] (F) Oh, the world outside is gone... (M) But down here, we’ve still got fun! [Verse 1] (F) I really should go — the vault door’s closed. (M) But baby, it’s cold in the vault. (F) The Geiger’s hum’s startin’ to grow. (M) Just think how warm you’d be in my coat. (F) I wish I knew how to say no. (M) You’ve got no choice — the elevator’s broke! [Chorus] (Both) So let’s just stay where it’s cozy and bright, Forget the end and hold me tight, (F) We’ve got rations, and I don’t mean salt, (M) Oh baby, it’s cold in the vault. [Verse 2] (M) Your hair looks fine in emergency light. (F) You sure know how to flatter, all right. (M) I made us cocoa from recycled brew. (F) If it glows blue, I’ll blame you! (M) The overseer’s gone, the clocks are wrong, (F) Guess we’ll be here all night long. [Chorus – reprise] (Both) So bolt the hatch and don’t you sulk, No better date than post-cataclysm bulk, (M) We’ll cuddle up while systems halt, (F) Oh baby, it’s cold in the vault. [Bridge – playful spoken lines] (F) You said we’d have a view of the stars. (M) Well, technically, we’re beneath them. (F) Hmph — romantic. (M) Practical! [Final Chorus] (Both) When morning comes and the lights flick on, We’ll still be safe from what’s gone wrong, (F) You’ve got charm I can’t default, (M) Oh baby, it’s cold— (Both) In the vault! [Outro – laughter fading into soft jazz outro]
