Edgardo Donato (Spanish pronunciation: [eðˈɣaɾðo ðoˈnato]; April 14, 1897 – February 15, 1963) 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 [es]".
It became a standard, which later had English lyrics and a verse melody written by Bob Musel.
[1][2] The latter adaptation was titled "Tell Me Marianne", and spent a week at number 1 on the British sheet music charts in June 1947.
