Hogwarts Song

anybody know that song from the hogwarts prisoner of azkaban trailer? i think its from one of Shakespears works. i really want to know them. it starts with
"trouble, trouble, cauldron bubble" or something like that.

ah well, cauldron bubble can be found in Macbeth, but I'm not sure about all the other lines.

The song is by john williams, the lyrics are taken from macbeth but changed.

Double, double, toil and trouble
Fire burn and cauldron bubble
Double, double, toil and trouble
Something wicked this way comes

Eye of newt, and toe of frog,
Wool of bat, and tongue of dog,
Adder's fork, and blind-worm's sting,
Lizard's leg and owlet's wing
Double, double, toil and trouble
Fire burn and cauldron bubble
Double, double, toil and trouble
Something wicked this way comes

In the cauldron boil and bake
Fillet of a fenny snake
Scale of dragon, tooth of wolf
Witches' mummy, maw and gulf

Double, Double toil and trouble
Fire burn and cauldron bubble
Double, Double toil and trouble
Fire burn and cauldron bubble
Double, Double toil and trouble
Fire burn and cauldron bubble
