The Noisettes Breaking Dawn Soundtrack Band?

One of our astute readers made the connection that the band the playing in the honeymoon Comic Con clip was the Noisettes, and that the song was Sister Rosetta. See this entry http://www.twilightlexicon.com/2011/07/26/low-resolution-honeymoon-scene-from-comic-con/#comments Previous Twilight films have all gone with original music, and the above video dates back to 2007. So maybe a break in tradition, or place holder music. Either way, what do you think?
