"The Eight and Forty Sisters" (in Gaelic "Ochtar Deirfiúr is Daichead") is an Irish reel in E Dorian (Breathnach, Roche) or E Minor (Darley & McCall). The parts are played: one part (Darley & McCall), AB (Breathnach) or AAB (Roche). The ‘B’ part of Darley & McCall’s version of the tune is shared with "Dublin Lasses".
The melody, particularly in the B part, is similar to "The Musical Priest". Breathnach’s has a different second part. This version is from Bancalari.
It was printed in Breathnach's CRÉ II (1976), Darley & McCall's Darley & McCall Collection of Traditional Irish Music (1914), Roche Collection (1982) and Bancalari's Celtic Encyclopedia (1999).
