Was Gamehendge "One Night Only!!!" or was that a proto-shot at an actual musical run?

I have not watched the performance as closely as our intrepid blogger, but something really hit me during Tela - both Forbin and Tela were *really* selling the emotion of it, and Page appeared to be into it on a whole different level. At that juncture, I allowed myself to think, "They could be setting this up to be ... like ... a real musical. This could be just a very dry run, adapted for a rock and roll concert performance."

'twas just a feeling, but speculation is fun.
