The band’s fans are split between the rock fans of the 70’s; the original band, and the ballad audience of the 80’s and 90’s.  When I was preparing for this segment of under the classic rock, I tuned into an old video of the band, and a younger associate saw the clip and asked who the band was. I said the original Chicago. They were floored! They had no idea of the hard rocking origins of the band.
