Festival promoters are now saying that the Sun-Times got it wrong in their estimations of 60K more fans in Grant Park this summer for Lollapalooza. But they're still making me do a lot more math in my head and not giving straight numbers on new attendance estimates.

By my count, "10-15% more" = 7,500-11,250 additional ticketholders per day at the festival which could mean attendance rises from 75,000 to 86,250 (rather than the previously reported increase up to 95,000). That's a max total of 33,750 more ticket holders for the festival (about half what the Sun-Times estimated yesterday).
