You get pdf of a score of the arrangement, and an mp3 of a live performance of the arrangement. Peter Amidon arranged this in August, 2009 for a Union Sunday worship service of three area UCC churches at Brattleboro's Centre Congregational Church. The worship leader asked Peter for "Here I Am" as an anthem, so Peter turned the piano/unison hymn into this a cappella SATB version. A few years later Peter received this email:Dear Sir, I am the titular organist of Monaco Cathedrale. I'd like to play your beautiful arrangement of "I, the Lord of sea and sky" on the great organ but without voices, for a great mass in November with the Prince Albert Family. I will play the music for the Prince entrance in Cathedral on the 19th of November 2016. It will be a great mass for the Fête Nationale Monégasque. It will be broadcasted on TMC Channel. Thanks a lot and sincerely yours, Olivier Vernet...and so he did.
