No, Paul didn't go to Neil's funeral and Ringo didn't either. And I think they did it out of "respect" for Neil's family because they knew it would turn into a media "circus" if they showed up. Stella McCartney was there, as was Ringo's wife, Barbara Bach, and Yoko and Olivia. With all the hoop-la going around Paul's recent divorce from "the Heather", I think Paul thought if better not to show. Besides, I read that he was in NYC at the time Neil died or the day before, somthing like that.
