David Bowie nearly refused to sing a christmas duet with Bing Crosby, but the collaboration ultimately went ahead. The reason for the potential refusal is not entirely clear, but it is reported that Bowie's mother was a fan of Crosby and may have played a role in convincing him to participate. The duet, which was a performance of "Little Drummer Boy", has been described as a christmas classic and a notable collaboration between the two artists.
