Oh, man, I am a big Chicago nut! I've got all of their albums on CD, and all that were released on LP, except the collections! 1. "Saturday in the Park," by from Chicago V 2. "25 or 6 to 4," from Chicago II (and the infamous remake on Chicago 18) 3. "Does Anybody Really Know What Time It Is," from Chicago Transit Authority (their first album) 4. "You're the Inspiration," from Chicago 17 5. "Colour My World," from Chicago 2 Numbers 1, 2, 3 were written by Bobby Lamm, keyboardist and quite often social conscience of the group. Number 4 was written by Peter Cetera, and it appeared on his last album with the group. Number 5 was written by James Pankow, as part of the "Ballet for a Girl in Buchannon," which was essentially side 2 of the original two-LP album.
