Domenico Modugno, singer: born Polignano a Mare, Italy 9 January 1928; married Franca Gandolfi (three sons); died Lampedusa, Italy 6 August 1994. DOMENICO MODUGNO was known all over the world as 'Mister Volare'. The nickname came from the refrain 'Volare, oh, oh-oh' of his 1958 hit song 'Nel Blu Dipinto Di Blu'. Modugno explained that he wrote the song while thinking of a painting by Chagall, of a man, with half of his face painted blue, looking out of a window. With 'Volare' - which has become, along with O sole mio, the most famous of all Italian songs - Modugno won his first Grammy Award and sold 30 million records.
