Peace on Earth/Little Drummer Boy is a Christmas song with an added counterpoint performed by David Bowie and Bing Crosby. "Little Drummer Boy" is a Christmas song written in 1957, while the "Peace on Earth" tune and lyrics were added to the song especially for Bowie and Crosby's recording. The song was recorded on 11 September for Crosby's 1977 television special, Bing Crosby's Merrie Olde Christmas. The pair exchanged dialogue about what they do for Christmas before singing "Little Drummer Boy" with a new counterpoint with original lyrics written for the special, "Peace on Earth". Bowie's appearance has been described as a "surreal" event, undertaken at a time that he was "actively trying to normalise his career" Crosby died on October 14, just over a month after recording the special. In the U.S., the show aired on 30 November 1977 on CBS. More about the song at Wikipedia below: http://en.wikipedia.org/wiki/Peace_on_Earth/Little_Drummer_Boy
