At Cornell, my old a cappella group's signature song was a clever-ish take on "We Didn't Start the Fire" rewritten as, yes, "We Didn't Go to Harvard." Every few years my beloved Cayuga's Waiters would update the lyrics. And the song became so popular, the group eventually printed t-shirts, seen here. (Apparently they didn't sell well, because you can still buy one here.)
Anywho... someone went and posted "We Didn't Go To Harvard" and its lyrics on YouTube, in what may be the first case of a cappella karaoke. Enjoy.
