White Christmas is a classic holiday song written by Irving Berlin in 1942. It was originally performed by Bing Crosby and has since become a staple of the Christmas season. The song has been covered by many artists over the years, including Frank Sinatra, Barbra Streisand, and Mariah Carey. It was also adapted into a film in 1954, which starred Bing Crosby and Danny Kaye. The song speaks to the beauty and nostalgia of a winter wonderland and the desire to have a "white Christmas" each year.
