The Wurlitzer Theatre Organ at Brentford

" ... These amazing instruments, with their myriad of sounds were then used to provide musical interludes and to accompany the stage acts which formed a part of many cinema programmes back in the 1930s. The hundreds of organ pipes, the percussion instruments and the many sound effects which make-up this unique instrument were tucked away behind the decorative proscenium of the cinema and were connected to the illuminated console containing several thousand wires. ...
When re-installed in the Musical Museum, the organ was connected to a very rare Wurlitzer Automatic Roll Playing Cabinet, enabling the performances of many American Theatre Organists of the 1920s to be faithfully recreated. "
