This arrangement of "America" is played on the Holzhey organ of St. Peter und Paul Weissenau.
For Memorial Day I thought it appropriate to play it again. I used in our church services yeaterday along with the hymn, "My Country 'Tis of Thee".
In February of last year I did my first recording of this piece on the demo sampleset of the St. Michael Zwolle organ:

The original piece this is based on was "God Save the Queen", the anthem of the United Kingdom, and later used for "My Country 'Tis of Thee", as one of the original anthems of the United States. It was later replaced with "The Star Spangled Banner".
I'm not sure who wrote this particular arrangement, but it's one that I find very satisfying and not too difficult to play.
