Is the Go Go man an islander, possibly samoan or Fijian who yells out GO MORRIS GO MORRIS GO MORRIS. And he usually yells out the wrong name, apart from morris, soward, creagh and "the guy who go to parramatta"
Naa, caucasian with greeying hair, i used to see him at Wollongong all the time and at ANZ for a qualifying finals day where Saints were in both the lowers and Cronulla v NZ was first grade
Didnt see/hear him at Kogarah for the Newy game i went to earlier this year but spotted him just around from where me and my daughter sat last week and he was clear as during the NYC Lol
As for the signs I love the work that has been put into them all but my fave 3 are
Till i Die - i love the sentiment in that one and the stickman with Penfolds sponsor is awesom
GST - Great St George Team - Loved it when i first saw it years ago and it still holds up and a grab i love saying when watching footy with my mates
The Stewie sign - i love the work that has gone into it and it really caught my eye when it was picced on the back of the Mercury after the Cronulla @ Kogarah win
