Several versions of this quadruple chant are known. Three are found in the Cambridge University Library archive:
- The earliest version (1970) is the quadruple chant for Psalm 12. ATBB & organ in C minor(CUL catalogue entry).
- Then we have quadruple chant for Psalm 12. SATB & organ in E minor (CUL catalogue entry), Chant 12b from the 1970s/80s Caius Psalter in E flat minor for SATB*, and the version for Psalm 13 for SATB & organ in E flat minor (CUL catalogue entry). The SATB versions might be assumed to date from the period 1982-1989 when the Gonville & Caius College Choir added a soprano line.
