I saw the Kenshin/U2 video when I saw the music 
video exhibition at A-kon this year.  It was 
INCREDIBLE.

Try checking out the A-kon board.  A while back 
someone posted there looking for it also.  Maybe 
you can find the thread and see if that person 
got an answer for it. Or maybe you could try 
looking for the other videos there as well.

Good luck!
