The life and career of legendary E Street Band saxophonist Clarence Clemons will be the focus of the upcoming documentary Clarence Clemons: Who Do I Think I Am?

The project has been in the works since well before Clemens’ 2011 death, says director Nick Mead.

“He’d go out with his sax and I’d follow with the camera, and we’d ‘see what happens’ — we’d say that to each other every time we’d go out,” Mead says.

“When Clarence passed away, we had to rethink the entire film. Clarence’s life was one long ongoing journey. He was never satisfied with what had been achieved, he always wanted more.”

The film will feature interviews with a bevy of celebrities, including former president Bill Clinton, Joe Walsh and Nils Lofgren. It’s due to hit theaters in July.
