In the songs for special occasions in Spirit and Song Vol 2 we come to a series of songs celebrating saints. This one by Bobby Fisher and Greg Lee is a bit bland and suffers from mechanical verse texts, but the optional coda of alleluias is actually quite interesting musically. It also goes a bit high for assembly use if you think this would fit a liturgy.
The text is at spiritandsong where the sheet music can be purchased for download, although what they list as verse 2 and 3 are actually just verse 2. You can hear the original here.
