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
