This Saturday night don’t miss a great treat with GJRockestra at Robinson Theater. This show should be called Decades, as GJRockestra will play killer hits from 50’s, 60’s, 70’s, 80’s and the 90’s. You can get tickets by going to gjsymphony.org or at the door. The doors open at 7pm and the show will start at 7:30pm. If you have never gone to a GJRockestra show, this Saturday night is the one to go to.
