Brendan, re āglamorā, Websterās, the standard of American language, shows glamour as the preferred spelling, and glamor as an alternate, so I think the sketch is close enough.
Interestingly, a lot of places are reverting to ātheatreā from the more American ātheater.ā I was told by the head of the ātheatre departmentā at the university where I taught, that it was to make it seem artier (my word) or dare I say more glamourous. I donāt know, however, if it was to copy the Brits or the French directly.
