Sent this yesterday but never saw it come through, so I'm trying again:

Hey, so I'm trying to track down this song:

"Muhammad... Muhammad Ali / He floats like a butterfly, and stings like
a bee / Muhammad... the black Superman / He calls to the other guy, I'm
Ali... catch me if you can"

I heard it on WXYC a while back and it sounded for all the world like
Cat Stevens/Yusuf Islam, but I can't find any references to that song
on-line, beyond a couple of people of wondering out loud about it.  Who
actually did it?  What's it called?  Album?

Thanks!
Chris
