The songs that the editors of the Praise to God hymnal sourced from the Lutheran hymn book, All Together Again, are mostly Protestant folk songs, and they give an idea of repetoire that was suggested in the 1970s for Australian Catholic churches. I grew up with songs like these in the Presbyterian church and they were a welcome respite from what my young self thought were boring slow hymns played to the same few tunes.
This one is by Max Dyer, and once again Godsongs is all over this song. I also have a copy in Scripture in Song Book 2, and your best bet for sheet music is an old second hand hymnal. The chords are all over the internet, though, and that is probably all you need.
I made a backing:
1 I will sing, I will sing a song unto the Lord. (3x)
Alleluia, glory to the Lord.Chorus:
Allelu, alleluia, glory to the Lord.
Allelu, alleluia, glory to the Lord.
Allelu, alleluia, glory to the Lord.
alleluia, glory to the Lord.2 We will come, we will come as one before the Lord (3x)
Alleluia, glory to the Lord.3 If the Son, if the Son shall make you free, (3x)
you shall be free indeed.4 They that sow in tears shall reap in joy (3x)
Alleluia, glory to the Lord.5 Every knee shall bow and every tongue confess, (3x)
that Jesus Christ is Lord.6 In his name, in his name we have the victory (3x)
Alleluia, glory to the Lord.
