Christmas songs, below, from two remarkable singers:
The first recording is of a 1944 radio performance by Judy Garland, singing "Have Yourself a Merry Little Christmas." The song is from the 1944 film Meet Me in St. Louis, which starred Ms. Garland (and in which she, famously, sang the song).

The second recording is of Nat King Cole, singing "The Christmas Song" (often referred to as--and often subtitled--"Chestnuts Roasting on an Open Fire"). Mr. Cole released multiple recordings of the song, over time. The version below was made in 1953; the orchestra, for this recording, was conducted by Nelson Riddle.
