FANS of Pop Idol winner Will Young set a sales record of their own on Monday when they besieged Tesco's Watford Extra store throughout the night to snap up thousands of copies of his debut single.

Amazed staff at Watford Extra served a never-ending stream of fans well into the early hours of Tuesday after the single "Evergreen" went on sale.

While many high street music shops reportedly ran out of copies during the day, Tesco's 24-hour stores ordered in extra copies and saw demand peak at 2am.

Tesco entertainment category director Mr Steven Garton said: "Will Young fans turned night into day for Tesco staff at many of our stores. We're calling it Will Power as we've never seen anything like it ever before.

"Pop pundits say this single's going to make history and be the fastest seller ever. It already has made history for us as we've never had so many music sales through the night.

"Despite Will Young being a hero to teenagers the huge popularity of Pop Idol has made him a hit with mums and dads as well."

Sales of the single "Evergreen" took off as soon as they went on sale at 9am and remained steady during the day.
