The Weird Sisters

In Harry Potter and the Goblet of Fire, we get to witness the equivalent to an American prom: the Yule Ball.  Hermione, dressed to the nines, is escorted by professional Quidditch player and heart-throb Viktor Krum.  Instead of a DJ, they get treated to a special performance by the rock phenoms known as The Weird Sisters (taken from Shakespeare's Macbeth).  Franz Ferdinand was originally cast as the band, but due to touring conflicts, had to bail out and were replaced by Jonny Greenwood and Phil Selway of Radiohead (!!!) and Jarvis Cocker of Pulp.  Magical indeed!
