Version 2 (Original version according to Gary Lester's book, and at least one verse of the song as sung by the team after a win):
Up, Up Cronulla
The boys in the black, white and blue
Up, up Cronulla
We're all depending on you
Sharks, Sharks forever
Go out and play without fear
Now's the time to see good football
For the Sharks are here
(Up the Sharks!)
By: Brother John, De La Salle Cronulla
* 'is' was in the lyrics from a 1977 Big League song list by Frank Hyde, 'hits' was shown on the screen at some games in 2004.
Version two is right, as per the 1973 Ray Warren 2GB Manly v Cronulla Grand Final single record. I have a copy!
