I guess action noise is pretty well inevitable on an instrument of this age, last overhauled in 1968. The noisiest action I have ever heard is the combination action at Marlow Parish Church, where it sounds as though a barn door is slammed with every piston push!
Much more annoying is the way the Beeb still clips the crescendos quite audibly - they have always done it (not just in organ concerts) and I can only assume it is a bad habit that dates from the earliest days of recording.
On a more positive note, they actually broadcast an ORGAN RECITAL!! Is this a much looked-for change of policy? David Goode's playing was clean and accurate, miles removed from some of the 'big names' I have heard fluffing recently. The organ sounded splendid in a well chosen and varied Easter programme. Well done to all involved.
(As an aside, the best two live performances I have heard for ages were both at the excellent 'Organ Workshop' in the Albert Hall shortly after the completion of the restoration - Clive Driskell Smith played the Allegro from Widor VI magnificently and Martin Baker gave an improvisation which knocked the spots off David Briggs' ramblings at the inaugural concert).
