The internet, the radio, and everything in between has been filled today with tributes to David Bowie. His music and voice are everywhere; even the classical station out of Interlochen, Michigan, played a portion of his 1978 recording of “Peter and the Wolf.” So I thought that instead of playing something everyone has heard, I’d find a piece that may be a little less known — and a bit out of season — but it’s beautiful. Not only that, it is a duet with one of the great voices of popular music of another generation: Bing Crosby in his last Christmas special from 1977. It was made (obviously) before Der Bingle died in October of that year, but the network put it on anyway. They made a great team.
