Harry Moses Simeone (May 9, 1910 – February 22, 2005) was an American music arranger, conductor and composer who popularized the Christmas song "The Little Drummer Boy", for which he received co-writing credit.
[1] He grew up listening to stars performing at the Metropolitan Opera in New York City, not far from his native Newark.
[1] After garnering vocal and music arrangement credits for the 1938 RKO motion picture Radio City Revels, Simeone relocated to Hollywood with his wife, Margaret McCravy Simeone, who briefly sang with Benny Goodman's orchestra, using the stage name Margaret McCrae, and later with Fred Waring.
"The Little Drummer Boy" was issued as a single and quickly became extremely popular and scored on the U.S. music charts from 1958 to 1962.
Under his direction, that group produced a baseball-oriented song called "It's a Beautiful Day for a Ball Game", which many major-league teams played at their ballparks or used to open their radio/TV broadcasts.
