When there are a lot of notes and no one knows the tune, it's easy for the extra bits to get in the way. I spent some time working out a different arrangement, based more on chords, that would sound all right but suit the instrument and be easier to follow. This sounds cleverer than it was. I just left out a lot of notes, basically.
The sidesman appeared waving the bottle of Communion wine. It was nearly empty. We studied it and decided that someone had taken some to take to one of the retirement homes for a service, and hadn't thought to let one of us know. "The Sage has got a bottle of port I brought him from Portugal. I'll fetch some of that." I provide the Communion wine. It's an entirely appropriate gift from me to the congregation, to buy decent port for the occasion. You have to have a fortified wine, regular red wine tastes thin and doesn't keep. So, I pedalled home and explained to the Sage, who was quite perturbed. "You won't take much, will you?" he asked. I told him that I wouldn't, and that I'd buy more next week for the church.
I took it along and chatted for a few minutes to the people who had arrived. Finally, "what time is it?" "Two minutes to eleven", I was told. "I'd better fill an awkward silence while we wait for the Rector and the rest of the conversation, then" I said as I hastened back to the organ.
It was noticeable that I'd practised in the past week, as I played better than usual. The Rector arrived and came to speak to me. "Everything all right?" she asked. I nodded. "I couldn't find the words I'd printed out for that new hymn," she said. "Can you find something you know well for the second hymn instead?"
So, I spent a few minutes looking up the Bible readings and finding something suitable. I did. I've already forgotten what it was, but it was fine. I've got another funeral to play for on Friday, so will be well practised by then. I can coast along without much effort for weeks afterwards.
