Famous piece of music. In my youth I heard the music and from hearing wrote the notes. Later when the music was published it appeared that my notes were very correct except with the choral/ This music is from the original notes as published.
This 2nd version is a bit slower (the title is "Rest my Soul, thy God is King" And I got some advise on performing. I also switched manuals conform the music instruction.
The video is still the version 1 (bit faster, other registration, less manual switching) for 'benchmarking :)
