Looking further at Fiona Dyball’s presentation of road tested repetoire of music for prayer and devotion there is:
Fill Us Up by Fr Rob Galea
Dyball notes this to be a prayer about God’s love, which is fair enough. The text is here and the sheet music can be purchased in a collection at GIA. I couldn’t find it at As One Voice anymore.
Healing Waters by Trevor Thomson
This is a song that could be used in a sprinkling rite but is also a sung prayer about mercy. The text is here and the sheet music can be purchased at OCP.
Hold on to Love by Jesse Manibusan
She notes this to be a prayer of hope. The text is here and the sheet music can be purchased at OCP.
How Can I Keep From Singing?– traditional – another prayer of hope – Dyball notes Audrey Assad’s version.
The text and sheet music are at OCP, but the tune is public domain and can be sourced elsewhere.
