In 1957, several cities were vying to host the 1964 Winter Olympics. Candidates had been eliminated to the point where the only two left were Singapore and Nevers, France. The French venue had an obvious advantage for the games, but the Singaporeans were eager to host the games in their country, so they developed a snow-making machine. Because of technical glitches, the machine produced snow only part of the time. The rest of the time it produced steam, and you can't ski on steam. So they made a last-ditch effort to perfect the machine, knowing that the deadline for a decision from the committee was nigh.
To bring moral support and entertainment to the workers, they brought in Elvis Presley, who mounted the stage and said, "Well, today's the day your machine must produce snow. If it belches out steam, the games will go to France. So this is it. It's snow, or Nevers."
