They are just magnificent. I saw them do this in 1992. Just pure talent and excellent stamina. No wonder they look at the audience when they finish a move as if to say " See? This is what we do. We can. You can't. But we can and we'll show you more". Of course the rippling muscles that owe itself to an exercise regimen is what I kept not trying to watch but they just kept popping in front of my face and just made me look at them. A-hem.. cough, cough,....
