Once Upon A Time In America (Deborah’s theme) guitar tabs. From Sergio Leone’s movie of the same name. Once Upon a Time in America is probably the most beautiful music Ennio Morricone ever composed. “Deborah’s Theme” was written for another film in the 1970’s, but was rejected. Later, Morricone presented the piece to Leone who was initially reluctant to include it. He considered it too similar to Ennio’s main title music for Once Upon a Time in the West. Despite being the last collaboration between Morricone and Sergio Leone, Once Upon a Time in America is a perfect end to their legendary legacy.
