Some air, some fire, some water, too,
Four walls, a roof, a kitchen and a loo,
Some friends, so i don't feel alone,
And my mobile phone

Some clothes, especially me jeans
Bacon and tins of heinze baked beans
Mars, Snickers and Tobleron
And my mobile phone

Me fridge, my freezer and my TV
And digital camera and DVD
And the cool gear that I've outgrown,
And my mobile phone

And Adidas, Nike and satellite dish
A friend, and love, and meat, and fish
And make-up, and perfume, and cars, that go fast,
And hope that the future will be better tha the past,
and me Beatles CDs and my Pearl Jam Live

But if it was necessary, to survive
I'd giva up everhing i own
But my mobile phone
