There's an app for that

I'm sitting in the choir room with the Organist and a random tenor, trying to pick hymns for Sunday (the Organist has to be away, so I'm playing), and the Curate comes in. "I'm preaching on Melchizedek on Sunday," he says. "I don't suppose there are any hymns about Melchizedek. Be pretty hard to rhyme . . ."

I immediately think of Hymn 443:

From God Christ's deity came forth,
his manhood from humanity;
his priesthood from Melchizedek,
his royalty from David's tree:
praised be his Oneness.

No one else knows it, so we play and sing through it a couple of times. And everyone loves it. So I get to introduce a wonderful hymn to the congregation on Sunday.

Unfortunately, the pedal line is rather ambitious for someone as out of practice as I am.
