This is a delightful song for gathering and welcome by David Haas.
This was another song he sang at the Perth APMN conference and it was well received. He noted at one point that we should not be fearful of songs that hit Ds, but as a matter a charity I would be tempted to drop the key from G to F. They are six verses for a generous opening.
The sheet music can be purchased at GIA, where the text is in their preview and also here.
