I would like to back up David's post on Charterhouse organ. It was installed about 80 years ago and is excellent for supporting a lively chapel congregation; not ideal I agree as a recital instrument. It was last renovated 30 years ago by Harrison and probably needs a fair bit of rebuilding with updated electronics; some extra ranks could be added without changing its character. But to say this instrument has outlived its life is just wrong. St Marys Redcliffe is 100 years old and has just been rebuilt and the Royal Festival Hall is belatedly in the middle of a complete rebuild. Is anyone suggesting that organs once played by Bach should be stripped out and dumped?
