So much talk about immigrants. You know one thing is that if they did not exist you would have to invent them, and this whatever those who rant and rave to the contrary, and perhaps this evening will joyfully sing White Christmas without knowing that it was written by Irving Berlin, a Russian immigrant of Jewish origin who spent his life between New York and Los Angeles. It was Berlin himself who wanted Bing Crosby to sing his song. He knew, and how right he was, that Bing’s flute-like voice was perfect to arouse that both soft and sad romantic sentiment which characterizes the song throughout. Since 1942, Crosby’s version of the song has sold more than 50 million copies and can claim to be the world’s most sold single, and dedicated to all who see the world in an array of colour.
