I saw Chicago when they were Chigago Transit Authority. They put on an excellent concert and jammed every song. I saw them after they became famous and the concert was very dull. Every song played just like the record. I thought that, after all these years, they would be better. They aren't. No jamming here. Every song done as the original with maybe a couple short variations. I was very dissapointed. They are capable of doing some good concerts but I really can't say that this is one of them.
