Mandela's voice

You migh have heard Nelson Rholihlahla Mandela saying the following words in an Olympics commercial:

For seventeen days, they are roommates.For seventeen days, they are soulmates.And for twenty-two seconds, they are competitors.Seventeen days as equals. Twenty-two seconds as adversaries.What a wonderful world that would be.That’s the hope I see in the Olympic Games.

Don’t you love his voice?
I might use it when I teach.
