The video is a must-see even though the comments at the link are atrocious and just show how shallow (of thought) and emotionally-driven are those who hate the president. Either way, I think it is still a fun video and recommend you watch it: President Bush singing U2's "Sunday Bloody Sunday." Or just click the play button below ... and you might have to click it two times.
Another thing: Michael in comments at the link points out that the last line is omitted in this version. Hmmm? I wonder why. Could it be because of the meaning of those words?
The real battle yet begun / Sunday, Bloody Sunday
To claim the victory Jesus won / Sunday, Bloody Sunday
Sunday Bloody Sunday / Yeah
Sunday Bloody Sunday
