For several years, English rugby supporters have used 'Swing Low, Sweet Chariot' as their unofficial anthem. It's got a great chorus, but the verses are uninspiring, and anyhow, most people can't remember them. So how about borrowing a couple of verses from Mr W Blake, and inserting them between the choruses of 'Swing Low' , like this:

Swing low, sweet chariot: coming for to carry me home (2X)

Bring me my bow of burning gold; bring me my arrows of desire
Bring me my spear – oh clouds, unfold - bring me my chariot of fire

Swing low, sweet chariot: coming for to carry me home (2X)

I shall not cease from mental fight, nor shall my sword sleep in my hand,
Till we have built Jerusalem, in England's green and pleasant land.

Swing low, sweet chariot: coming for to carry me home (2X)

It might be worth a try ...
