Which Is the Best-Selling Single of All Time?

'White Christmas' was written by Irving Berlin and first sung by Bing Crosby in the 1942 film Holiday Inn. The song won the Academy Award for Best Original Song and became hugely popular with homesick soldiers during World War II. Crosby re-recorded it in 1947 because the original master recording had worn out from being pressed so often. Guinness World Records recognises it as the best-selling single, with sales estimated at about 50 million. Elton John's 1997 'Candle in the Wind' is generally considered the best-selling single since charts began.
