Edgardo Donato was a tango composer and orchestra leader. Born in Buenos Aires, Argentina, he was raised in Montevideo, Uruguay, where he was musically trained. Donato composed the 1924 tango "A media luz". It became a standard, which later had English lyrics and a verse melody written by Bob Musel. The latter adaptation was titled "Tell Me Marianne", and spent a week at number 1 on the British sheet music charts in June 1947.
Donato died aged 65 in 1963.
