It's funny how a throwaway comment can generate such interest! What I meant was the name Brian Day reminded me of Brian May, who was a member of the legendary rock group Queen, and two or three days later I couldn't remember (without looking at the cover of the book, which I didn't have to hand) if the author had been B. May or had just reminded me of B. May. So I erroneously went with the former when it should have been the latter.
I was also admitting I was wrong so you could say I was being Queenly then, if the current thread is anything to go by. Argh!
