In his book Big Man: Real Life & Tall Tales, Clarence Clemons recalled the origins of the Born to Run album. "In the beginning, I think Bruce was going for a rock opera kind of thing about this character called Magic Rat," Clemons wrote. "He had lots of songs and themes that were built around this narrative he had in his head. Eventually he let that go." The Magic Rat did make it into the album's epic closer "Jungleland," which contains Clarence's most famous sax solo. In the summer of 2009, they played it at London's Hyde Park right as the sun was coming down. Check it out here.
