Reminds me of the Mohammed Ali story, think it was Parky told it. The guy arrived into the uk, maybe 10-15 years ago, straight off a flight from the states, got mobbed by fans, stood there and gladly signed every autograph and spoke to every person.
If a dude with parkinsons off a 9 hour flight can manage can do it and even be humble about it, then noone else has any excuse
