*Quoting Rees and Rees in Celtic Heritage (1961) who quote P.D. Hardy in The Holy Wells of Ireland (1836) quoting the Book of Rites.  A Wiki search on the Book of Rites yielded a 1962 translation of the Book of Rites.  The idea expressed above, about language and music,  can only be intuited from this translation. The website which includes this translation fo the Book of Rites is a rich resource for Celtic history
