Never got to see Chicago. Had a chance to L&F in Santa Rosa last year but that was the same week we go camping.
They will be in Irvine on June 12, 2021. Hope that will work for you!
I never saw Chicago, either. I did see a Chicago cover band called Beginnings, at a local park. They were really good, and a lot of people were thee. In another universe, I am a singer in a cover band—I do a great Cetera, Lamb and Kath. At least it sounds good in the car at night.
