Don't want to spoil the party but Widnes have a Ste Tyrer version that's been sung over last few weeks
It's all come about as widely spread due to the new Liverpool Luis Suarez song getting lots of publicity. As said originally in sport I believe its a Celtic song with the exact words as on 1st page here (Celtic for Wigan of course).
If you can get it going who cares sounds great IMO. But you weren't the first in RL
