I was listening to Opie and Anthony this morning and I heard them play a mash up of George Bush singing the U2 song Sunday Bloody Sunday. After doing a little googling I was able to find the song on beatmixed.com. It was made by DJ RX who has done some more of these Bush mash ups, including one to My Generation by The Who. You might need to register at his site to hear the rest of the song but you could download Sunday Bloody Sunday here.
