Hahahaha! Yep! That's about how I remember it too!
It's polite. It's just a memory aid. It's not brilliant it is just a sketch while drinking coffee eating toast. Drawn with a stubby pencil, a stubby pencil that would be better employed marking a score card for a round of golf, It's just a thing on the back of the envelope that contained a royalty statement that pays nothing. It kind of made me laugh to myself. I don't think I have drawn anything since.....(that's a lie) but no I haven't really drawn a thing since.
