I stumbled on this video, and it got me to thinking.. How in the world did they do this? Did anybody here see Yes "in the round"? Did they just walk though the audience to get to the stage? Or just appear in a cloud of fairy dust? LOL! Where were their stagehands and techs? I could understand a permanent "arena theatre" stage in a playhouse. But this mess was trucked all over. It was spinning around for crying out loud! How did the cables not get all tangled up like a phone cord does? LOL! How did they do this logistically? I like the little glimpse of the stage under the house lights prior to the show. I think this video, though kind of poor, is pretty fascinating. How such a huge-selling band could have so little professional-quality video footage surviving is such a shame.
