Four versions of this double chant are known. Three are found in the Cambridge University Library archive:
- The earliest version (undated) appears to be the double chant for Psalm 75. ATBB & organ in A major.
- Then we have double chant for Psalm 75. SATBrB & organ in D major and the version for SATBrB & organ in E flat major. These versions might be assumed to date from the period 1982-1989 when the Gonville & Caius College Choir added a soprano line.
