This is a setting of Psalm 139 by Paul Inwood. It has his usual inventive style and the refrain is singable (OK there is a held D). The verses will need the cantors for which it is designed. I think sheet music should warn you if the 4/4 is going to go random like this does in the verses.
The text is in the sample at WLP where the sheet music can be purchased.
I had no idea how to get the backing right, especially tempo and feel so this is a bit of a fail.
