I promised some reflections on the Arizona holiday, and this was probably the funniest thing that happened to me during the course of it - although it actually happened on the plane from Phoenix to Chicago at the start of our return trip.
As I am fetching something from the overhead compartment, a middle-aged American guy in the seat behind (who actually looked a little like Danny De Vito though I didn't tell him so) taps me on the shoulder and goes: "Aren't you that guy out of Genesis, Phil wotsisname, Phil Collins?"
I politely assure him I am not although I do confess to being a bit of fan and to having seen the great men on their reunion tour in Manchester last summer.
I have actually been mistaken for Mr Collins once before, but that was over 25 years ago, when we both had hair. Perhaps the question I really should have asked my De Vito-lookalike was whether he really thought Phil Collins would be travelling economy class?
