Iron Maiden's upcoming world tour is pulling-in the punters.

The Nordic leg of Iron Maiden's "Somewhere Back In Time" world tour has proven particularly hot, with three stadium dates in Sweden and Finland selling out in less than 150 minutes, according to the band's representatives.

The two sold-out Swedish shows are to be held July 16 at the Stockholm Stadium, and July 26 at Ullevi Stadium, Gothenburg, with respective capacities of 31,500 and 50,500.

Organizers have added another Finland date, July 19 at the 30,000 capacity Ratina Stadium in Tampere, after all 41,500 tickets sold out for the Helsinki Olympic Stadium concert on July 18.

"You must appreciate that Helsinki has a population of half a million," comments promoter Thomas Johansson of EMA Telstar, "so this is equivalent to selling out a dozen Wembley Stadiums before lunch."

And in Columbia, the band's local promoter for the concert at Bogota's 30,000-capacity Simon Bolivar Stadium, says Iron Maiden is in box-office-busting mode.

"We sold over 12,000 on just the first day," says Phil Rodriguez, promoter for the band's Columbia leg. "Nobody has ever done this, it's fantastic - this is usually a 'slow' market for ticket sales."

The band's tour kicks off Feb. 1, 2008 at the Bandra Kurla Complex in Mumbia, India, before trekking on to Australia, Japan, the Americas and Europe.

"Everywhere tickets have gone on sale so far," comments the band's manager Rod Smallwood, "we have had a tremendous response at the box office."
