Here's a funny story about Sha-Na-Na that my mom told me - I don't remember the actual occurrence, because I was really little (some time in the late 70's.) I LOOOOOVED Sha-Na-Na. I watched it religiously and would dance to every musical number on the show. I was a huge fan of Bowser (the guy with the deep voice.) Well, as kids do, I humiliated my mom at K-Mart with a simple kid-like statement ... we were in line at the checkout, and there was a big, muscular woman in front of us with greasy hair. And I pointed at her and said, loudly and with great glee - "Look Mom!! It's Bowser from Sha-Na-Na!"
The woman was not nearly as thrilled to be Bowser as I was!
