I'd only be lurking in the background, not actually performing.
My brother had to actually get quite abraisive with a South African TV crew once who wanted him to read THAT passage from Hamlet for them. He explained, as a resident, not a tourist, and not being part of the actors guild he couldn't actually do it as he would probably get a visit from some RSC heavies. Probably Iain Glenn (Jorah Mormont in GoT) who was played by Henry V at the time.
He was in his School uniform at the time. KES liked forcing their boys to promote the school.
Someday I will get to the RSC. And my son and I want to take in a match at Goodison Park.
