The most-recorded song of all-time? The biggest-selling? That would be Irving Berlin’s “White Christmas.” “It has been recorded in Dutch, Yiddish, Japanese and – perhaps most surreal of all – Swahili. Its sales have topped 125 million worldwide and its place as the all-time top single has been challenged only once, not by the Beatles, not by Presley nor Sinatra, but by Elton John’s ‘Candle in the Wind 97’ tribute to Princess Diana.”
