In 1979, aged 17, I was a volunteer helping install a new pipe organ in my home church in Motherwell in the west of Scotland. That resulted in the loss of the tip of my left forefinger. It was bloody painful, funnily enough!
Tomorrow, having taken a day of flexi-leave from work, I have been persuaded to help a friend install an Allen organ in St Andrew's Roman Catholic Cathedral in Glasgow, which has been closed for renovation since 2009 and which is due to open again this coming weekend.
Wish me luck, I need all the fingers I have left!
