There's a guy who posts images of old newspaper ads for the theaters in my home town now and then. Today, he posted one from November 8th, 1963. Look what was advertised on the page! (Following is my comment to the post)

Upper left corner. The Kingston Trio at the West Chester County Center. I went to that concert. I was then and still am a huge Kingston Trio fan! It was my first concert of theirs. One of many! And my first concert ever. My Mom and my Aunt drove me and my best friend to see the show. I still have my ticket stub! Thanks for posting!
