"Defying Gravity" lyrics

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
