In 1967, five musicians had a dream to integrate all of the musical diversity of their city and weave a new sound: rock 'n' roll with horns. Since then, Chicago has written, recorded, and performed some of the most popular and best-loved songs in rock history. This performance includes such favorites as Hard Habit To Break, Saturday in the Park, Does Anybody Really Know What Time It Is?, Color My World, and 25 or 6 to 4.
