He's not going to leave himself open to anything here...
"Hi Francis, great to meet you. My question is, why did you go behind Rick and Alan's backs, re-record their vocal parts, then go to the record label and presented it as your own and then have the neck to turn around and say, "Oh I can't work with these two, particularly Alan, anymore" despite the fact those two were quite happy to meet you half way?"
"Why did it take you almost 5 years, between 1984 and 1989, to make a meaningful songwriting contribution to a Quo album, despite the fact you now claim Alan and the band were holding you back?"
"Why did you fuck up your guitar sound?"
"Why do you continue to take the piss with your playing, as if you really don't want to be there?"
"Why did you say that about Matt?"
"What's the real reason for Matt leaving?"
"Why were you so enthusiastic about writing Heavy Traffic but, then acted as if the material on QPQ was beneath you?"
"Did going bald affect your attitude to playing rock music?"
Does anyone really think those questions will be asked? Or, if they will even be allowed?
