Maybe Si, Maybe No

Can you sail, my friend, on the stars?
Can you run on the wind over the Sahara?
Can you dance, my friend, on the ocean floor?
Can you sing with the breath of a fly on a moor?

Can we do the impossible?
Can we do what we can't?
Can we change the whole world,
With just a single glance?

Maybe si, maybe no...
Maybe both of the two
Nothing's for certain and nothing's for sure.
