Bruce Springsteen thrilled fans by turning up unannounced at the screening of his documentary in London on Friday night (29Oct10).
The rocker took part in a question and answer session after his film The Promise: The Making Of The Darkness On The Edge Of Town was shown at the annual BFI London Film Festival.
He spoke openly about the movie, which features never-before-seen footage of his E Street Band shot between 1976 and 1978, telling audience members how the archive film was found.
Springsteen revealed, "The guy who shot all the footage was the kid in the neighbourhood who had the camera. He wanted to be a film maker at some point. It wasn't going to go anywhere so we weren't worried about it.
"He'd come up the studio with his video camera and he was easy to ignore. Then he sat on it for 30 years. He was good about it... he said, 'I don't know, is it mine or yours?' I paid him for that so I guess we sorted that out, but it was good of him not to do anything for 30 years!"
The documentary accompanies new box-set release The Promise: The Darkness On The Edge Of Town Story, due to hit shelves next month (Nov10), and the star told eager fans about new tracks featured on the release.
He says, "We made a lot of music... and the music that was left out was truly a separate record. We stumbled our way to 10 songs (that made the record) and they've stood up over the years. There's a lot of beautiful music we had a chance to finish over the summer and I hope people get a kick out of it."
