Jerusalem. Think outside the religious aspect of it, and it says all it should - "I'm going to do everything I can to make this country wonderful". Not powerful, or rich even, just wonderful.
Some time back I came up with a cyclist's version:
And did those wheels, in happy times,
Turn upon England's lanes so fast.
And was the chain, all lubed and clean,
over the sprockets smoothly passed.
And did the cranks, so smoothly spun,
propel us onwards, mile on mile.
Soothing the rider with their hum,
and on his face putting a smile.
Bring me my bike, my perfect wish.
Bring me my map, to find the way.
Bring me my shorts, Oh padded bliss!
And from my route I shall not stray.
I shall not cease from pedalling,
Alone or in a happy band,
'til we have built a cyclists' dream,
In England's green and pleasant land.
(for a national anthem, replace 'England's' with 'all our'.
