Fundamentally, it's our song. no other club sings it, or uses the tune in any song. It's ours, it's our heritage. The club itself have used the tune for years as the team runs out onto the pitch. Norman Wisdom, jumpers for goalposts, stand or fall.
It's interesting that early on in the season, if you listened to radio Sussex, you'd distinctly hear "win the cup". On Monday, I thought it sounded more like "stand or fall".
