Chicago is a completely different band then years ago but this is a tour I would not mind seeing. Too bad this did not happen many years years ago. I saw Chicago several times back in the mid/late 90's and they were always very good. On their "NIght and Day" tour, we were in the 5th row and it was very memorable...no opening band, just them. Also saw them at the I-Cubs baseball stadium (now Principal Park) but it is just not the same as when you are so close...but, still fun, a Saturday game and a concert is how it was sold.
So, I am kind of looking forward to this tour.
