I'm sitting right behind you in the church Terry. It sounds very realistic/magnifiicent to me. Interesting composition; the way it keeps skirting away from the main theme in almost a modern jazz, discord variation type of way and then returning to the central theme.....you hear everything here eventually!!
I never linked you with the tutorial but thanks for sharing that effort. The GPO organ, as I said, always sounds very realistic indeed to my undeducated ears, but as an organist how would you place it in the realism stakes?
