There are several versions of this song on the internet, I have the original score and a review of its’ first performance in ‘Gilles et Jeanne’ a semi-fictional play by Donald Reid  about Joan of Arc and Gilles De Rais in 1992 in the Edinburgh Fringe.

Here is the original manuscript :

Leanate is the only homophonic piece on the album Emotional Sense, obvious religious overtones, but with no meaning as all the words are a made up quazi French/Latin, just the enjoyment of that area of harmonious melody.

Reviews of the original show ‘Gilles et Jeanne’ staged in 1992 Fringe Festival.

and a performance at St Mary Aldermary back in 2014
