I just noticed that at the Chicago concert, they updated the footage. It now shows the End of an Era trailer on the big screen <3 (though obviously, it falls out of sync, both because the song's tempo is faster, and because they perform the full version)

Still think its really neat! My new goal for 2013: see Thancred on that huge screen at the next Distant Worlds show <.<

Here you can see the video:

And here is better audio (nalanol is such a Calloway groupie xD)
