The official Billboard Boxscore attendance and sales figures for 6 out of the 20 Rush shows so far on the 2013 Clockwork Angels tour were released over the last couple of weeks. There were no sellouts reported yet and ticket sales are down a bit from the 2012 tour according to these numbers. The highest-grossing and most-attended date on the tour so far was the May 24th show at the O2 in London. Note that the capacity figures reported do not always correspond to the actual physical capacity of the venue, but instead reflect the number of tickets that were made available for sale. I've already added the numbers to the tour section and have also listed them below.
