In one of the most successful duets in Christmas music history, and surely the strangest, 30-year-old David Bowie and 73-year-old Bing Crosby achieved the number one song in the UK with “Peace On Earth / Little Drummer Boy”. The song had been recorded in September, 1977 when Crosby was in Great Britain to tape a TV special called Merrie Olde Christmas. Having him share a number with Bowie was the brainchild of producers Gary Smith and Dwight Hemion. After the recording circulated as a bootleg for several years, RCA decided to issue it as a single. It has since become a holiday standard, but it is entirely possible that neither Crosby or Bowie were familiar with each other’s work.
