Oh Christ! It's NOT about AIDS!!! My interpretation? It's about Freddie finally coming to terms with his sexuality and killing off Farook Bulsara once and for all and at last becoming Freddie Mercury. In the commentary in the "Bo Rap" portion of the Greatest Hits dvd, Brian says that this was a time when Freddie was going through some personal issues meaning that his sexuality was not yet defined. As soon as he was more comfortable with who he was becoming, if you notice, that's when he started wearing the ballet outfits in the late 70's and the leather look on the 78-80 tours. Freddie had FINALLY arrived. But this topic is one of great discussion but this is my view on it. AIDS came around 1981.
I totally agree with you there, i always thought it was that, Brian did say that which helped me relise its more true then i was guessing, hes was becoming Freddie Mercury reinventing himself if you like, OUR SHOWMAN!
