Apparently there is going to be an announcement this coming week, about concert(s) coming to Wrigley next summer. The STRONG rumor is Pearl Jam, while the Rolling Stones are about to announce shows for their 50th anniversary sometime this week, starting with London and New York. I would imagine the Stones coud easily sellout 2 shows at VERY HIGH ticket prices. Pearl Jam, could probably sell out one show at best with much lower ticket prices.
For what its worth here's the link to the new Stones single. Not bad for a bunch of old dudes!
