Rhosymedre (3 Preludes on Welsh Hymn Tunes, No. 2)

Here it is at Salisbury, with a very similar, but not exact, registration.

If you listen closely, you can hear the "toe stud" thump as the 32' Open is brought on for the final note... ;-)

I do play the first in the set as well, so maybe I'll post that one soon.
