Hiya, i am not such a huge fan, my sis is a proper fan though, we went to see them live in Madrid years ago but then again Richie was missing already.
We took pics of them just before they got on their bus when leaving the stage, and my sis got an autograph from them all (but Richie obviously).
I can´t really say cos i dont know much about him whether he´s aspie or not, but he seemed shy and "different" actually, whether aspie or NT...who knows.., hope he still alive somewhere thou..,
