Lyrics
What is a summer really But a tepid month or three? Ferb: Clay Aiken? Phineas: ''Yeah. I hired a stunt singer. Whaddaya think?'' If you agree with Buford That's all it will ever be

And we don't need to break the laws of physics To make a day that's longer than a day We can follow that old sun 'round the circumference of the globe And stop all the naysayers from naysay...ing

'Cause I believe we can And that's the measure, the measure of a man It may sound far-fetched, this thing we've got planned But I believe we can

I believe we can (Ooh, I believe we can, I believe we can) And that's the measure, the measure of a man (Oh, that's the measure of a man) Phineas ''(to Ferb): Chaka Khan. Nice.'' We'll make it back here (We'll make it back here) to where we began...(Oh...) Phineas: Or at least that's the plan! Chaka Khan: Of course, first you're gonna have to fix this wing, yeah!
