As cool as it is to see this video of Bruce Springsteen & the E Street Band covering "London Calling," the downside of this is apparently, if you threaten the E Street Band with a sign that questions their ability to play a song, they must play it. For instance, if someone had thrown a sign onstage that said, "'Single Ladies' -did I stump E Street?," would they have played that instead? Readers going to see Bruce Springsteen, please keep this in mind.
