I still think Yellow Submarine would be a good choice.

Maybe with a tiny bit of rewriting, though I'd sooner do without even that:

We all live on an island in the sea
An island in the sea, an island in the sea
We all live on an island in the sea
An island in the sea, an island in the sea

And our friends are all aboard
Many more of them live next door
And the band begins to play

We all live on an island in the sea
An island in the sea, an island in the sea
We all live on an island in the sea
An island in the sea, an island in the sea

As we live a life of ease
Every one of us has all we need
Sky of blue and sea of green
On an island in the sea

We all live on an island in the sea
An island in the sea, an island in the sea
We all live on an island in the sea
An island in the sea, an island in the sea.
