-Intro− [Upbeat, major key, like a jingle] [Spoken, cheerful announcer voice] Hey there, Future Manager! Tired of the surface noise? Got that end-of-days dread? Then step right up! -Verse1- The sky's a bit gray, the world's kinda fried, But down in the Vaults we're safe and inside! With your Pip-Boy wrist-unit and a smile on your face, You're the future of Earth, saved by corporate grace! No more messy wars, no more resource plight, Just clean, sterile air and a fluorescent light! Your neighbors are vetted, your routine is set, A perfect, tiny world, the best that you'll get! -Chorus− [Very catchy, with layered harmonies] Join the Buds, Buds, Buds, Bud-dies! We're building better futures, beneath the dust and skies! You're not a test subject, you're a key demographic, For Vault-Tec's grand design, mathematically graphic! Be a good little Buddy, and manage the gloom, Till the night glows green, and we rise from the tomb! -Verse2- We run a tight ship, with systems so neat, From water-chip rations to what you can eat. The purpose of life? Well, we've got a whole chart, For the betterment of science, and the strength of the heart! Maybe your Vault's locked, maybe the Overseer's mad, But think of the data! The learnings we've had! A thousand small worlds, a thousand bright screens, We’re refining humanity's genetic means! -Chorus− [Faster, more intense, with a synth bassline] Join the Buds, Buds, Buds, Bud-dies! We're building better futures, beneath the dust and skies! You're not a test subject, you're a key demographic, For Vault-Tec's grand design, mathematically graphic! Be a good little Buddy, and manage the gloom, Till the night glows green, and we rise from the tomb! -Bridge− [Tempo slows, music becomes slightly unsettling and mechanical, minor key shift] [Spoken, distorted whisper over a theremin synth] The future needs leaders... and experiments to learn. Your sacrifice is logged... your data will burn. Vault 31, 32, 33... just the managers... Waiting to wake up and cash in the failures... [Music swells back up, but with a slight, manic edge] But every result is a step to the top! We’ll find the perfect human, we just can’t stop! -Chorus− [Full throttle, brassy, huge drums] Join the Buds, Buds, Buds, Bud-dies! We're building better futures, beneath the dust and skies! You're not a test subject, you're a key demographic, For Vault-Tec's grand design, mathematically graphic! Be a good little Buddy, and manage the gloom, Till the night glows green, and we rise from the tomb! -Outro− [Jingle returns, fades out with a happy−go−lucky robot voice] [Robot voice, chirpy] Thank you for your cooperation! Have a safe and productive experiment! Vault-Tec... always looking out for you! [A quick, sharp ZAP! sound effect]
