Where can you find information about the Syndrome a rock music venue in Chicago back in the late 1960s and early 1970s?
I saw Rod Stewart and the Faces there on Nov 13 1970. The Syndrome was formerly known as The Colisseum. This was known as the "second" Colisseum and it was located on Wabash Avenue, near the corner of 16th Street. The original one was on 63rd and Stoney Island. http://en.wikipedia.org/wiki/Chicago_Coliseum
XYY syndrome is an aneuploidy of the sex chromosomes in which a human male receives an extra Y chromosome. A popular misconception in the 1960s and 1970s that XYY males were more prone to criminal behavior led to several novels and TV series which exploited the idea with little regard to the science.
