Bing Crosby did a duet with David Bowie a few months before he died ("Little Drummer Boy"). Most know it as a classic Christmas song but there is a slightly longer version with some banter between Bing and David at the beginning. This is the version to get.
Little Drummer Boy/Peace on Earth with Bowie is what I remember seeing on one of Bing's Christmas special in th eearly 1970s. Those were alot of fun.
and the sirius Christmas music channel plays it about once an hour.
