Our Father Willis

Sadly Father Willis, (our beautiful pipe organ named after its maker) has severe bronchitis. He enjoys humidity and does not like the current dry atmosphere combined with the heating on in Church. He has never suffered so badly before and there is a probability that he may not recover without an extensive (and long overdue) reconditioning.   We have begun an organ fund to pay for the renewal but we have a long way to go. Do you have any suggestions?
