Goodness, a Marty Haugen song I haven’t heard before. This is an uplifting song of joy for times when that might be hard to find. The verses are designed as call and response between a cantor and assembly but it could just be sung straight through by parishioners if you don’t use a cantor. The tune has a hint of “Alouette” to it.
GIA sells the sheet music here and the text is in their preview. The first two verses can also be found here.
