America the Beautiful -- An Internet Choir

I would like to hear America the Beautiful sung by ten million voices. I'm not sure it is technically possible. The idea is that a common set of lyrics would be published on the internet along with a common key and exact metronome-based timing. Then people could perform and record it, either individually or in groups. The performances would be uploaded to a central site where they would be mixed.

I know it is a somewhat grandiose/silly thought, but just the thought of all those voices singing and feeling these great lyrics kind of grabbed me -- even if it never actually happened. Here are the lyrics currently on Wikipedia.

America the Beautiful
by Katharine Lee Bates

Oh beautiful, for spacious skies,
For amber waves of grain,
For purple mountain majesties
Above the fruited plain!
America! America! God shed his grace on thee,
And crown thy good with brotherhood, from sea to shining sea.

Oh beautiful, for pilgrims' feet
Whose stern, impassioned stress
A thoroughfare for freedom beat
Across the wilderness!
America! America! God mend thine ev'ry flaw;
Confirm thy soul in self control, thy liberty in law!

Oh beautiful, for heroes proved
In liberating strife,
Who more than self their country loved
And mercy more than life!
America! America! May God thy gold refine,
'Til all success be nobleness, and ev'ry gain divine!

Oh beautiful, for patriot's dream
That sees, beyond the years,
Thine alabaster cities gleam
Undimmed by human tears!
America! America! God shed his grace on thee,
And crown thy good with brotherhood, from sea to shining sea!
