BBC has a show called Time Trumpet. It's set in 2031 and is supposed to be a light entertainment show looking back at the 2005-2010 era, using clips, interviewing celebs ( a 60 yearold David Beckham for instance).
Anyways they had a neat clip of George Bush speaking the lines of Imagine (crafted together using soundbites from speeches) set over the backing track to Walk On The Wildside. Condaleeza Rice did the dodedo bit after "and all the cloured girls go.." which was used as a chorus( a bit un-pc I know, but call it satire and you can do what you want).
Very wierd but very well done.
