Douglas - the pump system is automatic and normally works well. What it can't legislate for is if stupid electricians turn the elctrical supply off for days over an unattended bank holiday.
As far as the organ is concerned, there are discussions taking place about it. Without jeopadising the situation, there is more than a distinct possiblity that the organ will be re-homed. Its presence in the hall is considered 'difficult' and that the hall is now used for many other events which could not have even been perceived in Prof. Evans' time. Because of this, the organ's integrety and safety is often compromised. Secondly, there has always been a real difficulty regarding the use of the instrument. This is partly due to the hall being owned and administered by one branch of the university, and the organ being owned and managed by the music dept. The Tuner Sims Concert Hall organ is not owned by the hall itself. This has caused no end of 'difficulty' for students and other interested parties actually getting access to the insturment, and there is more than a distinct feeling that the access to the instrument would be enhanced if the instrument were placed in a more accessible situation.
