John Morton Downey was an American singer and entertainer popular in the United States in the first half of the 20th century, enjoying his greatest success in the late 1920s and early 1930s. Downey was nicknamed "The Irish Nightingale". Downey began his singing career as a member of the choir of Most Holy Trinity Church in Wallingford. Downey's signature sound was a very creamy and very high-timbred Irish tenor, which an uninformed listener can easily mistake for a female voice. The popularity of such highly artificial and "heady" male pop vocals peaked in the late 1920s and early 1930s. By the mid-1930s, the style was out of fashion, and Downey reduced some of his broader mannerisms and made a transition to a somewhat more "chesty" vocal timbre.
