Posted there by Dave himself, as it happens.

The tune at the hymn sites I mentioned above is quite different. Which, I wonder, was the original setting?

Incidentally, beware the second link I provided above. On re-visiting it, I found that every single audio file on the page started playing simultaneously; each had to be turned off individually as the page (slowly and painfully) loaded. Didn't happen when I first found it. The experience was moderately interesting in a surreal sort of way, but I wouldn't recommend it to the easily-disturbed.
