I really fell in love with this tune by William Lloyd Webber (to be heard on a cd of the Choir of All Saints Margaret Street London, available on Spotify). The original version is for choir, with continuous organ accompaniment. This is my try of changing the piece into a hymn for congregational singing.
The first verse is more or less Lloyd Webber's harmonization (approximately, because I did it by ear), the other two are my own. Unfortunately, I could not find the text of this wonderful hymn...
