With "live" you mean, in person ??? or on TV live coverage of his matches ??
Well, if it is in person, I have seen him several times thanks to my God and since long time ago...:
--IW and Miami 2002
--IW and Madrid 2003
--IW and Miami 2005
I had here, the opportunity of asking him 2 questions for a news paper... LOL
--IW, Miami, Toronto and Madrid 2006
All have been wonderful.... he has been always gorgeous (during practice I mean with this tennis and with the people) Hope to see him soon again !!!!!!
Will post some pics later (Should I post them here or there is a thread for this ??)
