Defying Gravity

I live on a big round ball I never do dream I may fall And even if one day I do Well, I'll jump off and smile back at you I don't even know where we are They'll tell you 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 So when I do fall, I'll be glad to go I live on a big round ball I never do dream I may fall And even if one day I do Well, I'll jump off and smile back at you
