Not only he was there, fully bekilted, dagger in sock, he also got to meet Prince Michael of Albany (a Stuart of course, who would have been king today, if Scotland had been an independent kingdom). Indeed, Mike marched most of the way alongside him, among the Prince's bodyguards. So it would not be surprising if you saw him on TV. Local London News did not show the march, but BBC Scotland would have. Mike would have stood out not only by his size, but also because he was wearing a simple white shirt on top, which would have stood out among the jackets.
