The London bus and subway bombings barely made a dent in ticket sales at the BBC Proms. After an initial dip at the beginning of the festival (which occurred between the July 7 bombings and the second attempted attack on July 21), sales were robust throughout August, and the final tally will likely be down only 2% on last year. More than 20 concerts in the massive Royal Albert Hall sold out, and overall capacity was better than 80%, a big success in a venue more than twice the size of the average concert hall.
