Okie, guys and gals, uber uber thanks goes to whoever can tell me the track of the song i'm going to describe. i heard it about a year ago, and have looked desperately all over the place. this is what i remember:

it was in a video for a "renaissance" thing and it has part of martin luther king's i have a dream speech in it.

again, i've looked everywhere, and i would really like to figure it out. thanks a billion
