My mind is a complete blank about this Michael Joncas song. It looks like a Holy Thursday song, but could be for any Eucharist, as it really is material for about five songs, just pick a verse of two.
GIA sell it in this collection, but it is also in Gather Australia and Gather Comprehensive, I gather.
I have no idea how it is supposed to sound so my backing is rather speculative.
This works well for the washing of the feet during Holy Thursday services.
