Mary Gentle Mother is a bilingual Australian Christmas carol, that may also be sung as a SA duet or a unison or solo song, in English and / or Noongar Aboriginal language. The Noongar Aboriginal language edition of this carol, Mary Moorditj Ngaangk, is available on ScoreExchange as a parallel text English and Noongar SATB edition, a SA duet edition, or a guitar chord chart for solo or unison singing, to cater for singers of varying linguistic and cultural origin. This bilingual Australian Christmas carol was composed on 28 September 2000 for the composer’s mother, Olive Alison Simpson, and first sung as a solo by the composer in 2000 at a Village Life Goulburn (NSW Australia) community concert. The English SATB version was premiered on 24 December 2007 by Cantor Elizabeth Sheppard with St Patrick’s Cathedral Choir, conducted by Precentor Bernard Kirkpatrick and acompanied by organist James Dixon, at St Patricks Cathedral Parramatta. In 2018 Elizabeth rearranged her notated SA edition of this work as a notated vocal / instrumental ensemble, and this version was performed in November 2018 by Elizabeth Sheppard, mezzo soprano Sonya Holowell and Ensemble Offspring (Claire Edwardes, Freya Schack-Arnott, Lamorna Nightingale and Jason Noble) at the 2018 Ngarra-Burria Australian National University School of Music Studio Concert. Elizabeth’s original solo soprano recording of Mary Moorditj Ngaangk is available on iTunes and Spotify.
