I'm not talking about songs like Jack is the Daddy-O or The Game (We Didn't Start the Fire). Though those are great, I was wondering what songs are sung at Irish Football Matches (as I have never had the chance to go to one). I know You'll Never Walk Alone was sung at Stade de France. I figure Que Sera Sera and maybe The Battle Hymn of the Republic (the same tune as We're not Brazil we're Northern Ireland) are because they are general football songs, any others (lyrics would be great)?
