Wow Richardh, glad to read about the history of that such an original Pipe Organ! Just checked it out in the Wiki and it's amazing to know that it was built for the city's first dedicated concert venue in 1928, at that concert hall. This organ was described as "A Rolls-Royce" of organs, according to Wikipedia probably the only one still unaltered, as most comparable large organs have been modified, added-to or revoiced.
Just the opening track (Promenade) of that amazing ELP's live album was played on this pipe organ istalled in the Newcastle City Hall - suprised to know the importance of this Concert Hall as well, a venue for renowned orchestras and rock bands as well as for celebrity recitals in my greatfather's hometown! Yeah... Newcastle upon Tyne (Tyne the name of the river that crosses it), it is where he came from, sometimes this world looks small indeed!...
