If you haven't seen U2 and Green Day's music video, "The Saints are Coming", please take a moment and check it out here on MTV. Done as a part of the Music Rising project to bring the music back to New Orleans, the song debuted on ESPN, a cover of the Scottish punk band, The Skids.  

Watching this video is like watching an alternate universe, or a DVD where the alternate ending was so much better you felt somehow shorted by the director.  Only in this case, the original ending was reality.  Watch and you'll understand.  I wish more musicians used their influence to this kind of good measure.
