Where is John Deacon?
Bar a couple of public appearances, John retired once the Made In Heaven album had been completed.
Who was Death On Two Legs dedicated to?
In 1975, as A Night At The Opera was being recorded, Queen were attempting to extricate themselves from what they saw as an unreasonable contract with Trident, their first management company. It has always been generally assumed that Death On Two Legs was intended as a stab in that direction, although (possibly for legal reasons) the band never specified the exact target.
Having said that, when it was played live, Freddie would usually introduce it by saying something uncomplimentary about "a man we used to know"...
Why does my copy of Live Killers have beeped out speech?
See above.
Did Freddie really write Crazy Little Thing Called Love? I'm sure Elvis recorded it, too.
Yes, he really did, no matter what filesharing sites say. It may sound a little Elvis-like (although this is more in feel than vocal performance), but it was written and recorded around two years after Elvis went to the great gig in the sky. However an Elvis impersonator called Orion did record a cover version of Crazy Little Thing Called Love.
I saw that Brian is credited with the music to a film I saw. Is it true?
If the film is Furia, then the answer is yes. If the film is Mad Max, Freddy's Dead - The Final Nightmare, or anything else, then the answer is no, it was an older, Australian composer who died in 1997.
Is No-One But You about Princess Diana?
No. It's about Freddie.
