Our chapel is much like yours but in the desert it is nestled into an adjacent hill. Three wards meet there using the overlapping block system of 9am,11am,1pm. Since our ward meets at 1:00pm no wards follow and we hold Priesthood meeting last and in the chapel. Music in PH meeting has always been delegated to the Aaronic Priesthood members to lead.  Seldom did we ever have accompaniment.

Then we exchanged our old organ for a new more adaptable one. The deacons soon found a way to use the organ on automatic mode. To every one's surprise one young man perched himself at the organ prior to the opening hymn of priesthood meeting. Much like using an iPod, he played a introduction followed by the full hymn.  What we heard was a melodious and 'normal' sound as notes were magically produced. I looked to see who on earth was playing. It appeared as though no one sat there, then a brim of this deacon's head appeared. We were all stunned,,,,and delighted at their ingenuity.  I reached for my iPhone and took this picture just to recall this cheerful event for later.
