Can U2 still pack stadiums?
Considering the records they've already broken on this tour, that shouldn't be a problem.
Since announcing the tour in early March, U2 has sold a staggering 2.5 million tickets, including the fastest-selling, most-attended Rose Bowl concert ever and the largest single-day sales records in New York (82,000 tickets sold), Boston (72,000 tickets sold) and Chicago (65,000 tickets sold). The band also has broken several European sales records, from Zagreb to Spain.
The lesson should be clear: If you want tickets, don't delay.
