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 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
