I know CHICAGO had 3 lead singers, Cetera, Kath, and Lamm, up to 1985 or so, anyway, but I always thought Lamm did the early Hits, but then I read Kath sanf lead on "Colour my world"...right? if so, then I really don't know about the other pre-73 tunes...so, who sang lead on: Beginnings? Saturday in the Park? Dialouge (with Cetera) Make me smile Does anybody know what time it is? followup, while on the subject...Basically after "Dialouge" up untill He left in the mid 80's Cetera dominated...lead on virtually all the many Hits...why is that? I heard He left because the others were at odds over the band's musical direction and forced him out? Hello? why would it take about 12 years to decide they were unhappy with Cetera's Dominance?
