Just a small part of this World of your Nation you brag
And you wave your patriotism in your National flag
If your team win the International game today
Your boss won't give you extra in your next week's pay.

You feel so indifferent to people from elsewhere
Remember there's a World called the big World out there
And united we stand and divided we fall
Those words apply to all Nations and to one and all.

Tonight in the bar-room you will drink till late
And with your pub friends today's win celebrate
A win for your Nation in such a big game
Though only the players involved in the victory will know of the fame

And the financial windfall to them that this victory will bring
And of their praises you and those like you do sing
And are the supporters of the losing team worse off than you
Your pride in a flag tell me that is not true?

For pride of their flag young men go to war
And in victory boast of how marvellous they are
And for pride of their flag far too many have died
And so much division created by pride.

Francis Duggan
