But re London's 'multiple centres', Gibb: yes, true ~~ London is, like all huge conurbations, a collection of villages. But take one indication of which of these is really the centre: Theatres. Many 'villages' have, or have had, their own single theatre: Golders Green Hippodrome; Theatre Royal, Stratford East; Rainbow Theatre, Finsbury Park; Orpheum, Temple Fortune; The Ashcroft Theatre, Croydon; The Churchill Theatre, Bromley ... But the West End has ~~ how many? never counted; but googling London Theatre Seating Plans produced 45! And the general ambition of any company opening a production in any of these 'village' theatres, as well as in the provinces, is for an impresario to be found who will take it "into the West End".
