I think when Syd dies (hope that thing ain't gonna happen soon), the fans will be the "only" ones who'll cry for him. I don't think anyone else would be interested in it. The only thing I know for sure: I'd listen to Shine On and other Syd (or Syd related)songs till my pain goes (at least a bit) away...
