Question: Where was the singer of Ngarra Burra Ferra born? Passage:The track "Ngarra Burra Ferra" sung by indigenous artist Jessica Mauboy from the 2012 hit film The Sapphires is a song based on the traditional Aboriginal hymn "Bura Fera." The song is in the Yorta Yorta language and speaks of the Lord God's help in decimating a Pharaoh's armies. The chorus, Ngara burra ferra yumini yala yala, translates into English as "The Lord God drowned all Pharaoh's armies, hallelujah!" These lyrics are based on an ancient song in Jewish tradition known as the “Song of the Sea” or “Miriam’s Song”, as it was composed and sung by Miriam, older sister of the prophet Moses. It can be found in Exodus 15, especially verse 4, “Pharaoh’s chariots and his host hath he cast into the sea: his chosen captains also are drowned in the Red sea." Aboriginal communities of Victoria and southern New South Wales may be the only people in the world who still sing the piece (in Yorta Yorta).
