I think everybody is aware. If they were then they shouldn't expect them to go away. I just don't see what the Cubs get out of it. No one goes to the games or tunes into the broadcast for the stretch, so why give a free media junket stop for every movie star and musician? How often has sportscenter or some other entity shown the guest conductor? Wrigley probably accounts for 90% of all "look at the goofy thing that happened in the booth" stories you see out there. There is probably very little to gain for them from having the dregs come through, but every once in a while they get Eddie Vedder or some other A-list and it adds to the allure of the stadium. It also something they can market, both in terms of having something to offer corporate partners and random Chicago area prize winners, and in advertising dollars.
