I'm proud to announce the locations of that footage. The stunt kites were in Vanier Park , Vancouver, with the Burrard bridge in the background, and the other location is either Kitsilano beach or Jerico Beach, Vancouver,( just a bit further West). I did meet that guy once at a kite festival in Vanier Park. My dad was involved in that before he died , and took me along a couple of times.
That is a remarkable demo.And the music just fits so well. Keith
