and Steve Nelson, and first recorded by Gene Autry. It was written after the success of Autry's recording of "Rudolph The Red-Nosed Reindeer" the previous year; Rollins and Nelson shipped the new song to Autry, who recorded "Frosty" in search of another seasonal hit. Like "Rudolph", "Frosty" was subsequently adapted to other media including a popular television special "Frosty the Snowman". Source: Wikipedia
