I'm totally impressed with the speed that you are able to churn these out with. And in what appears to be a "single take" from your thoughts to the engraved score. Couple this with never having seen, nor perhaps even heard, this hymntune before. Very impressive J-Paul ... very impressive, indeed.
I'm going to have a busier than usual practice session on Thursday.
For my taste of preference for keys, I like the A flat version for organ solo ... for congregational singing we try to keep the top line out of the stratsophere.
