Defying gravity

I live on a big round ball
I never do dream I may fall
And even one day if I do
Well I'll jump up and smile back at you.

I don't even know where we are
They tell me we're circling a star
Well I'll take their word I don't know
But I'm dizzy so it may be so.

I'm riding a big round ball
I never do dream I may fall
And even the high must lay low
But when I do fall I will be glad to go.
Yes, when I do fall I will be glad to go
