song lyrics?

[benigs]

hey! i loved the trailer of PoA... i really loved the choir's song. i 
especially loved those large toads they were clutching. anyone notice 
that one of the toads is beating its head to the beat of the music? ;p

anyways, i was wondering if anyone has the complete lyrics of that 
song? if you do, can you please post them? and is it true that the 
line "something wicked this way comes" is from shakespeare? sorry, im 
not familiar with his writings... :)
