I can skip a lot of songs form OCP’s Guitar Accompaniment Book already blogged:
83 Bread of Life: Advent/Christmas Setting (Farrell)
Which brings me to Gregory Norbet’s communion song based on the wonderful passage from Didache 9. Take your pick of the six verses if you don’t need such a long song. I think it goes a little high for comfortable assembly singing – maybe take it down to F.
The text is at the Weston Priory and the sheet music can be purchased for download at OCP.
