I found a few very short (unfortunately) bootleg clips of Rush's show at the Red Rocks Amphitheater in Colorado from the R30 tour. Neil Peart declared this one of the "magical" shows from the tour in his book Roadshow and he used a picture from this show for the cover of the book. You can check out the bootleg clips at the links below.
