I swear theres already a thread about this.. I'd definately ask him about his cats, but in the russell brand interview, he declined to answer any feline questions - even the feline questions from RB humble mother, its all very personal.
Seriously though, I'd ask him why he never liked The Beatles. I think I once read that he said they had maybe four good songs.
It seems a little strange to me that as a little boy in England in the 1960s who was obsessed with pop music didn't like The Beatles at all. (He didn't like the Stones until later in life. They must have been too rock for little boy Moz.)
I’d ask him to meet me in Copenhagen and come to Bronnum or to the Library Bar for a cozy evening of lotttttttttttttts of gabbing. Undoubtedly, more giggles than anyone could even shake a stick at would be involved.
