This is Marty Haugen‘s take on Ps 136. There is a sample at AOV but don’t let that put you off. It looks like the whole song can be heard at Myspace, but I can’t find any other versions and I’m sure it would sound fine sung normally.
The text is here. (scroll down) It can be purchased in a collection of psalms at GIA.
My backing is at 100 bpm.
Thanks for posting this song. It was not easy to find this song elsewhere
