Another famous Chicagoan that turned out to be a royal douche is Peter Cetera. I knew him well back in the 60's when he played in a lounge band called The Exceptions. This was before his "CTA" days.. They were the most sought after lounge band in the Chicago area..Booked up for months in advance..He and myself went to the same music school. Marty Grebb's, who later joined the Buckinghams and sang lead on Mercy Mercy, dad ran the place. One of the guys , a successful studio player, ran into Pete(what he was known by before he got a big head), out in LA. The guy just walked up to him to say hi.. Pete remembered him of course but told him basically to buzz off and that he didnt want it to get around that he used to play in lounges in Chicago back in the day. It would hurt his reputation..Pete walked away and left this guy with his jaw dropped...
