T.G. ;Chicago bottomed out in 1991. After "kinda" nauseating radio listners in the 80s with their ballads (although I do like "Hard to Say I'm Sorry" w/the original jazzy ending).
When the 90s started,they had their last hit with "Chasin' The Wind" #39,which was similar to the annoying "Look Away".
Peter Cetera was lucky enough to last until 1996 but he simply teamed up with a then younger R&B group called Az Yet & their re-make of "....Sorry" which he sang part of. It made the top 10.
Now that's desperatly hungering for commercial success! :D
