Peter Tranchell wrote this setting of Psalm 23 (The Lord is my shepherd) in 1962 for unison voices and organ, revised it in 1970 for two-part male-voices and organ, and again in 1976 for ATBrB choir and organ. The score published here has been arranged for SATB by Peter Marchbank.

When PAT eventually bought a television he became obsessed with the Australian TV soap Neighbours (among other things!). He arranged the well-known theme tune (by Tony Hatch) as an Anglican chant - it was heard at least once in Caius chapel services, receiving the reaction ‘that seems faintly familiar...’ although the harmonisation is pure Tranchell. The composer's name is an anagram of "Neighbours", and the arranger "I'm astraan" i.e. Australian. The chant was probably written around 1987.
