question: When was the "Rudolph The Red Nosed Reindeer" song originally recorded?
short_answers: June 27, 1949
context: The song was first sung by crooner Harry Brannon on New York City radio in early November 1949, before Gene Autry's recording hit No. 1 in the U.S. charts during Christmas 1949. The song was suggested as a "B" side for a record Autry was making. Autry rejected the song. His wife convinced him to use it. The success of this Christmas song by Autry gave support to Autry's subsequent popular Easter song, "Here Comes Peter Cottontail." Autry's version of the song also holds the distinction of being the only chart-topping hit to fall completely off the chart after reaching No. 1. The official date of its No. 1 status was for the week ending January 7, 1950, making it the first No. 1 song of the 1950s.
