Ah-hah! Fast search (http://www.alltheweb.com) did it for me -

Winter is icumen in,
Lhude sing Goddamm,
Raineth drop and staineth slop,
And how the wind doth ramm !
Sing : Goddam.

- Ezra Pound, Ancient Music

http://www.gardendigest.com/winter.htm
- also contained an e.e.cummings quote:

the snow doesn't give a soft white damn whom it touches
