I found some postings on a music web site I frequent from a man who is part of a group called The Vitaphone Project, whose goal is to collect the shellac soundtrack discs that accompanied the early talkies. Don't know his name, just his handle. Anyway, according to him, Warner is working on a restoration of "The Jazz Singer," which we knew, but he did provide some details which are probably credible, given his involvement with The Vitaphone Project: - Warner is completely restoring the soundtrack using unplayed Vitapohone discs that still had the paper seals on them. - All the musical numbers in the film were originally shot in two-strip color, but these were not used for the release. According to him, Warner has found the color film for the "Mammy" number, and possibly the other numbers, which will be included on the DVD, though he doesn't know if the color footage will be integrated into the film. - He says he thinks the DVD will also include a deleted scene from the film that was found in a vault in the Netherlands, and some Al Jolson shorts done prior to "The Jazz Singer."
