I stumbled upon this topic by accident since I´m currently working on a "James Bond 2012 Gold Jubilee DVD Edition" - all the rare material I can dig up will find its way into that, together with all the stuff from my "archives". You know, things they just hold back on the official DVD releases.
Marrying the original audio from the workprint with the UE DVD footage would prove a nice challenge and I´d be happy to take it if someone wants to share the copy.
Cheers,
Benny
