Yeah, it must've been an email, because she was 100% sure it was true. It'll be really exciting to see how they actually use these "extras" in the performance. (For reference, my friend is a music student but not a professional singer or dancer, so I'm not entirely sure that the "extras" will be performing, per se--I would expect that they might be seated onstage on a small-scale replica of the Imperial set, and used as crowd singers and egg-shakers or something, similar to the recording session for the OBC. Of course, that would imply that the medley would use some part of the Abduction or Balaga, but who knows?)
