Question: What is the full birth name of the singer who sang "All Alone Am I"?
Sentence (from "El Greco"): "El Greco" was a nickname, a reference to his Greek origin, and the artist normally signed his paintings with his full birth name in Greek letters, Δομήνικος Θεοτοκόπουλος ("Doménikos Theotokópoulos"), often adding the word Κρής ("Krēs", "Cretan").
