For years I knew this as a bit of music-history xeroxlore. Only this year did I learn that it’s music-history xeroxlore by Ezra Pound. Who knew?

Winter is icumen in,
Lhude sing Goddamm,
Raineth drop and staineth slop,
And how the wind doth ramm!
Sing: Goddamm.
Skiddeth bus and sloppeth us,
An ague hath my ham.
Freezeth river, turneth liver,
Damm you; Sing: Goddamm.
Goddamm, Goddamm, ’tis why I am, Goddamm,
So ‘gainst the winter’s balm.
Sing goddamm, damm, sing goddamm,
Sing goddamm, sing goddamm, DAMM.
