My last album to pick from will be Chicago XI, the final album with Terry Kath in the group before his accident. With the shade green album cover showing a map of the city of Chicago and a few suburbs including East Chicago Indiana. Singles include "Baby, What a Big Surprise" "Take Me Back to Chicago" and "Little One" I always thought since Terry sang "Little One", it was in reference to his two-year-old daughter Michelle who would go on to make a documentary in her thirties about getting to more about her father and finding his favorite guitar with the Chicago Blackhawks sticker on it. But the song was written by Danny for his daughters.
I will add I did purchase and play Chicago's 12th album "Hot Streets" that included "Alive Again" and "No Tell Lover". As well as purchasing Chicago 13, with the neat album cover showing the twin Marina City buildings. The home setting for the "Bob Newhart Show" and the live studios of WCFL. Chicago's attempt with disco including Peter Cetera singing "Street Player" I enjoyed both, but it was not the same and after that I never purchased or followed another Chicago album.
My favorite non single track on Chicago XI is "Policeman" sung by Robert Lamm. Sad but strong. a track I played for my wife to use when she was looking for a song for her club's Hero Appreciation Night, but I could understand her passing on it
Bonus track is Terry singing "Mississippi City Delta Blues" opening song on the album
All in all, I could not have a better group to lead me through my grade school and high school years and hold on as a lifetime favorite. So good, when I play Chicago today I listen for pleasure not so much for past memories
