“White Christmas” is an Irving Berlin song reminiscing about an old-fashioned Christmas setting. According to the Guinness Book of World Records, the version sung by Bing Crosby is the best-selling single of all time, with estimated sales in excess of 50 million copies worldwide.
Accounts vary as to when and where Berlin wrote the song. One story is that he wrote it in 1940, in warm La Quinta, California, while staying at the La Quinta Hotel, a frequent Hollywood retreat also favored by writer-producer Frank Capra. He often stayed up all night writing — he told his secretary, “Grab your pen and take down this song. I just wrote the best song I’ve ever written — heck, I just wrote the best song that anybody’s ever written!”
