Freddie Mercury was on his deathbed when he sang this. When Brian May asked if he could perform the very demanding lyrics of this song, he consumed a glass of vodka and replied "I'll fucking do it darling". A few minutes later they started recording this song.
@Danfalc: That song comes in The Fast and the Furious. Like it too, but just to hear it once a week or so.::
You can always let me listen this: YouTube - Biggie Smalls - Hypnotize
