Just an old fans memory lane. Chicago bands from the sixties...

I was lucky enough to see them live do G.L.O.R.I.A.    The little venue was in Swisher, Iowa...I believe it was called "DanceMor Ballroom"  I did see Chicago both before and after Peter starting singing lead. 
But of course, does anybody really know what time it is, and that is assuming you can find someone that really cares. 

I had stayed at a friends condo at Lake Point Tower many times after he moved to "the burbs".  Many, many great memories of my time in Chicago, including wine tastings put on by some of the wine merchants.  I am always up for a meal at a Greek restaurant on Halsted. 

AHJ was 70’s
So was Styx
Siegel-Schwall were 60’s
A Lincon Ave. fixture.
Saw Corky & Jim in Galesburg
Shadows of Knight were from Prospect High in Mt. Prospect -The Knights
They were house band in my grade school cafeteria.
They headlined the Gilbert’s Festival with backup by REO Speedwagon from Chambana.
Fireworks, acid, rain and $1 Boone’s Farm bottles.
All good.

Rolling Stones at Chess.
