Triple chant for Psalm 127 for ATBB in C major, and for SATB in E flat major

Two (and possibly three) versions of this triple chant are found in the Cambridge University Library archive: 

• The earliest version (197-?) appears to be the triple chant for Psalm 127. ATBB & organ in C major.
• Then MS.Tranchell.3.68, the version for SATB & organ in E flat major. This version might be assumed to date from the period 1982-1989 when the Gonville & Caius College Choir added a soprano line.
• The archive also records MS.Tranchell.3.67 "For ATBB & organ in E minor [sic]. Photocopy of MS.Tranchell.4.86 with holograph revisions". Cataloguing error seems likely here, but we have not had a chance to check.

We are told this chant appears in the St. Paul's Cathedral ATB Chant Book (number 50) - thanks Peter Kirk.

[127]. PSALM CXXVII. Nisi Dominus.

1. Except the Lord build the house :
their labour is but lost that build it.
2. Except the Lord keep the city :
the watchman waketh but in vain.
3. It is but lost labour that ye haste to rise up early, and so late take rest, and eat the bread of carefulness :
for so he giveth his beloved sleep.
4. Lo, children and the fruit of the womb :
are an heritage and gift that cometh of the Lord.
5. Like as the arrows in the hand of the giant :
even so are the young children.
6. Happy is the man that hath his quiver full of them :
they shall not be ashamed when they speak with their enemies in the gate.
