This is a text by Graham Maule based on Luke 6:20-26 – the Sermon on the Plain – set by John Bell.
I can’t find the text anywhere (its a paraphrase of the Beatitudes alright) but there is a snippet to listen to at GIA.
It can also be purchased there very cheaply as part of the collection Love from Below. The same collection is also available directly from Wild Goose.
Their snippets are spirited and lively. My backing is more restrained.
