I can't remember if they had an organ, probably did.
It had a Compton 'Electrone' (non-pipe) organ shortly after opening in 1938 but this went to the Winter Gardens, NB, sometime later, according to 'The Silver Screens of Wirral' book, which has a photo of it. I seem to remember a 'La Fleur' organ there post-war. It was a rebadged Hammond electronic organ, probably for the kids' matinee sing-song. Remember those?!
