Their song, "Saturday In The Park", in which the lyrics mention, "Saturday in the park, I think it was the Fourth of July", gave me the idea for this thread. My favorites include - 1) "25 or 6 to 4", which is PROBABLY my favorite song by them. Their use of horns on this one is fantastic. 2) "Feelin' Stronger Every Day", just a wonderfully nice optimistic song. 3) Colour My World, my favorite slower song by them, this one is just beautiful, in both its melody and its lyrics. 4) "Saturday In the Park", I've loved this song since the first time I heard it. Just a wonderfully cheerful song. 5) "Beginnings", probably the first song by Chicago I heard as a kid. I believe I was most likely 10 or 11 years old at the time. I've always enjoyed the fantastic lead vocals in this one. Here are some of MY favorites, what are some of yours?
