Heavy metal band Iron Maiden takes the No. 3 ranking with totals reported from its Final Frontier World Tour that began in June 2010 with tour legs in both North America and Europe. The tour resumed in 2011 with a Feb. 11 concert in Moscow at Olympiski, a massive indoor arena built for the 1980 Summer Olympics. Attendance for the performance in Russia was 16,439 with ticket sales topping $2 million (US$). A show in Singapore followed on Feb. 15 with 9,785 in the house at the Singapore Indoor Stadium, the country's largest indoor entertainment venue. The veteran English band will continue touring this year with shows booked in Asia, Australia, Latin America and the U.S. before wrapping with a summer leg in Europe.
