Snakefinger i come from an island

I come from an island (listen)
I come from an I land
Rocks - all 'round our island there are rocks
On which our ships all dock
They crumble into grains of sand
Upon which our island stands
I come from an eye land (listen)
I come from a nigh land
Fish - that's all we get to eat here, fish
It is our national dish
But one day if our dream comes true
We'll barbecue a cockatoo
I come from an island (listen)
I come from an 'igh land
