An article from The Rocky Mountain News about Timothy Brock's work on the score "City Lights". Link to more>
"Brock assembled an early arrangement of City Lights in 1989 for the Chaplin centennial. In 2004, he returned to the film and created a complete restoration, digging through five boxes of manuscripts.
"The real challenge," Brock explained, "was deciphering all of Chaplin's revisions, since he would change things on the fly constantly." Notes and melodic snippets on scraps of music paper, restaurant receipts, what-have-you had to be organized into a cohesive, continuous score.
The difficulty in re-creating this and every other Chaplin soundtrack stems from the fact that he was self-taught and couldn't read music." - Rocky Mountain News, Denver, Colorado
