YOU'LL NEVER BEAT THE IRISH was written by Pete St. John. It is sung by The Dublin City Ramblers on their album "You'll Never Beat the Irish," Rego Irish CD #3015, 1993. The album cover says "The official song of the 1994 Irish World Cup Soccer Team."

It's hard to believe the lyrics of this song aren't somewhere on the Internet, but I failed to find them. The best I could do was to transcribe this much from a sound sample at allmusic:

Here we come, the Irish. Let me hear it. (Ireland!)
Here we come, the Irish. What a team! (What a team!)
Here we come, the Irish. Let me hear it. (Ireland!)
You'll never beat the Irish, and our mighty men in green.
