who wrote white christmas
From the White Christmas page, Steven Lewis' The Bing Crosby Internet Museum (excerpt, abridged) White Christmas was written in 1940 by a Irving Berlin for the 1942 movie Holiday Inn starring Bing Crosby and Fred Astaire. Berlin's assignment was to write a song about each of the major holidays of the year. But Berlin, who was Jewish, found that writing a song about Christmas was the most challenging.
