"Defying Gravity" Lyrics

I live on a big blue ball
I never do dream I may fall
But even the day that I do
I'll jump off and smile back at you

I don't even know where we are
But they tell us we're circling a star
Well, I'll take their word I don't know
But I'm dizzy so maybe that's so

I'm riding a big blue ball
I never do dream I may fall
But even the high may lay row
So when I do fall I'll be glad to go
