John Morton Downey was an American singer and entertainer who gained immense popularity in the United States during the first half of the 20th century, with his greatest success occurring in the late 1920s and early 1930s.
He was affectionately known as "The Irish Nightingale" due to his unique, creamy, and high-timbred Irish tenor voice, which was so distinctive that an untrained listener could easily mistake it for a female voice.
