I work at a show Springsteen used to like, and he would come to see it live with some regularity. He'd sit in the kitchen until the host was ready to come out, at which point security would kind of just nonchalantly walk him in to a seat that had been kept empty. At this time, no phones were allowed in the studio at all, security would confiscate them if they came out. We used to love watching the face of the person next to whom he wound up sitting, as they realized "holy crow, Bruce Springsteen is sitting next to me and I can't take a picture, text, tweet, or freak out. I just have to sit here and watch this show for the next 30 minutes."
