Difang Duana (March 20, 1921 – March 29, 2002) and Igay Duana (August 9, 1922 – May 16, 2002), Chinese names Kuo Ying-nan (郭英男) and Kuo Hsiu-chu (郭秀珠), were Amis husband and wife farmers from Taiwan who became known as a folk music duo who specialized in traditional Amis chants. Their most recognized work is a performance of a traditional Amis Palang song, alternately called "Weeding and Paddyfield Song No. 1", "Elders' Drinking Song", and "Jubilant Drinking Song", or Sapiliepah a Radiw in the Amis language. The song was recorded by a French government project and EMI, and was subsequently sampled by the musical project Enigma for their international hit single "Return to Innocence". Accusations of unintentional usage without permission were settled out of court.
