Cover art for The Curtain Close lyrics by Automatic Loveletter

To me it sounds like "This life, bring your tommy guns on the overload" I'm not sure if I'm right or not.

Lyric Correction

You would be correct. The OP has it wrong. It doesn't AT ALL sound like what they have posted. It even makes more sense to be "bring your tommy guns on the overload" due to the other line "So we'll leave with a bang at the curtain close."
