[Intro] Shoo-be-doo, doo-doo-da-doooo-doo, Shoo-be-doo, daa-dum... Shoo-be-doo, doo-doo-da-doooo-doo, Shoo-be-doo, dee-da-dum. [Verse 1] When the Chinese guys, They threatened all; And Vault-Tec knew, That the bombs would fall... They staked their dough, On a sure bet; Backed by government, And the corp execs. [Chorus] When the fight comes home, Shoo-be-doo, doo-doo-da-doooo-doo, And the bombs fall; Shoo-be-doo, daa-dum... Everyone head to your vaults, Shoo-be-doo, doo-doo-da-doooo-doo, And heed the Vault-Tec call. Shoo-be-doo, dee-da-dum. [Verse 2] We annexed Canada, And took down Mexico; Broke into commonwealths, And watched our prowess grow; Since the days of Hiroshima, And Nagasaki too; Nuclear power soared, And technology grew. But resources got, Pretty thin; And we weren't taking one, On the chin; So Power Armored troops, Marched on in, And thus the Alaskan war, Did begin... [Chorus] When the fight comes home, Shoo-be-doo, doo-doo-da-doooo-doo, And the bombs fall; Shoo-be-doo, daa-dum... Everyone head to your vaults, Shoo-be-doo, doo-doo-da-doooo-doo, And heed the Vault-Tec call. Shoo-be-doo, dee-da-dum. [Verse 3] The remnants of, The old U S of A; The Enclave, They'd come to stay; And after the bombs fell, They came out to play; But super mutants and ghouls, Got in the way; They don't want no, Mutant types around; So they tried disease, To take 'em all down; Just made more, So what were they good for? [Chorus] In Twenty-Two Seventy-Seven when you come out, Shoo-be-doo, doo-doo-da-doooo-doo, An' the world's full o' mutants, rads and drought; Shoo-be-doo, daa-dum... Everyone let's leave the vault, Shoo-be-doo, doo-doo-da-doooo-doo, Tell Vault-Tec, "IT'S ALL YOUR FAULT." Shoo-be-doo, dee-da-dum. [Outro] When the fight comes home, Shoo-be-doo, doo-doo-da-doooo-doo, And the bombs fall; Shoo-be-doo, daa-dum... Everyone head to your vaults, Shoo-be-doo, doo-doo-da-doooo-doo, And heed the Vault-Tec call. Shoo-be-doo, dee-da-dum.
