Peter Cetera is only one of the lead singers of Chicago. Robert Lamm sang some of their greatest hits including Color My World, Make Me Smile, and Saturday in the Park.
Re: Who Was the Best Lead Singer of Chicago? Cetera is legendary but I think the other two were better.. Bill Champlin gets my vote. Will You Still love me  and I dont wanna live without your love and look Away are the Best Power ballads of all time.
