I'm leading the singing this Sunday (1st Sunday in Lent, Year C) in my local parish. Here's the program I propose to use:
Opening: A Trusting Psalm (Kevin Bates, As One Voice I:115)
Psalm: Marty Haugen's "Be with me, Lord" (Psalm 91) (Gather Australia 53)
Offertory: Give us hearts renewed (Michael Herry, "Song of the Pilgrim")
Communion: Gregory Norbet's "Heal me, O God" (As One Voice Vol II:52) - just the chorus I think.
Closing: On Eagle's Wings (Michael Joncas, TIS 48 / Gather Australia 452)
The setting for the liturgy I use is a responsorial one (the people sing after me), Christopher Walker's Glastonbury Mass (taken from Music for the Mass edited by Geoffrey Boulton Smith).
Yes, I know that none of this is classical Catholic. Quite the opposite. But each piece has the following benefits:
1) They are easy to sing (well, Eagle's Wings can be tricky if you follow Joncas' suggested timing, but easy if you don't!) and fairly familiar to our crowd
2) The passages are fairly scriptural, and all are focused on God
3) there is a good link up with the scripture readings for the day and with the beginning of Lent
4) none of these contain any heresy.
