But your calculation is based on a huge assumption that it's completely empty for the other 6 months of the year, which isn't true. Also I think one of the World Cup crowds was about 5000 people (there were two). The Kerfuffle concert was in addition to the normal Thursday concerts. Not sure if you guys have been down there much this summer. There are a lot of people on a daily basis, and the size of the crowds for the major events is sometimes jawdropping.
