Thanks Sirob for your answer.

I'm not sure what George is trying to prove, because it's been established that it's not Camden Street.



The poster on the original photo says "A Gaumont Theatre".
Surely that would have been superfluous if that particular building was actually called Gaumont?

Besides, Ged's contact says it was the Savoy, in Brougham Terrace, and I'm happy to believe that.
