I think AFTER the first batch of leaks they got really careful but before 2006? Not really..

Also, I think these 'leaks' are demos or almost finished versions floating around in label executives notebooks or sitting on shelves of people who really don't care about GN'R or GN'R new songs as we do. They wouldn't know how to value what they have, really.... Like MLK recordings found on an attic a couple months back or the Frank Sinatra record stored so good that it was labeled as lost and refered to by the owner as just another disc...

Definetely A but not those songs you've mentioned (except maybe Checkmate)

Left overs from CD sessions were widely spread even before Chinese Democracy released. I got a friend who worked for Universal at the time (from 2004 to 2009) and he got to hear, in a meeting regarding CD, most of what would be the CD II. I already posted his impressions on the subject a few months ago. The plan was to release CD and then tour US with a big act co-headlining and mid-tour release CD II. The songs he heard were identified as finished and delivered to release.

Think 50+.

The show was broadcasted in Japan this weekend.

Commentary / introduction program
London overwhelming broadcast live May 2012 Isy Sutoradorin of the original members became cameo since 2006, in the O2 Arena!
Since its formation in 1985, sheets 42 million in just the United States, reign as the legendary rock band both in name and reality in the world to record the album total sales covering more than 100 million, this year, and played a filled "Rock and Roll Hall of Fame" It, Guns N 'Roses. Although not what the announcement of a new after original album, "Chinese Democracy," which was released in 2008 spent a cost of ¥ 1.4 billion years and 14, and caused a great response every time you perform live, their impact I can not see a bit of the force decline.
From the European tour "up-close-and-personal tour" they like that was held in 2012, the pattern of the live broadcast on WOWOW made in the O2 Arena in London on May 31. Or there is a significant delay of the start times in concert in Manchester just before, but London show was kicked off with the news but troubled as ever, will be expanded performance raging as if vent frustration do, excitement of the audience is I reached to peak at once. Track List of "Chinese Democracy" is, of course, many of the masterpieces that cover all carriers, such as "Welcome To The Jungle" "Rocket Queen", but we will showcase Surprise maximum, 1991 guitarist of the original members who left in the year, the appearance of Ji?í Sutoradorin. Everyone in the audience is suddenly surprised to participate in the first time since 2006, who worked a lot of name players early work of the band, and let out a whoop of joy. The show will send exhaustively scenes that valuable. "14 Years" "You Could Be Mine" "Night Rain" "Paradise City" is played is a permanent version just sprinkled with Izzy.

Checkmate is that 30 seconds in a loop (that sums to up to 1 minute and a half) of "all cautions made, every chance was given, no efforts spared to save what we had"...

Blood In The Water is the most recent, that has the orchestration of Prostitute with some new vocals by Axl singing "blood in the water, (there will be) blood in the water" with a hip-hop beat.
