Since forming in 1967, Chicago has become one of the best-loved and most successful rock groups ever, thanks to their incredible sense of pop-savvy and innovative use of horns.  Their mind-boggling catalog of hits includes “You’re the Inspiration,” “Saturday in the Park,” “25 or 6 to 4,” “Feelin’ Stronger Every Day,” “Does Anybody Really Know What Time It Is?,” “Hard To Say I’m Sorry,” and the Grammy-winning “If You Leave Me Now.”  With 18 gold albums, 20 Top 10 hits, and five #1 records to their credit, Chicago remains one of the most widely-recognized American rock bands.
