I don't think Slash and Duff would bring the kind of music to a present day GNR record you guys think they would.  Headspace, Big Machine and Superhuman could have made a 1996 GNR record with Fall To Pieces, but those days are long gone.

And my main point was: most of the best songs on CD were made by current members.

Izzy's stayed neutral in this whole thing.

Q: What was the last straw that made you leave GNR?

Izzy: After the first leg of  the UYI tour, Axl wanted to make me sign a
contract which meant that I was less involved and less paid. I couldn't
believe it. This contract was coming from someone I grew up with for fuck's
sake. We always considered GNR as a best friend band, and now Axl was
telling me:" now we are doing business." Why should I carry on? Where was
the fun? That was the last drop.

Q: Do you still see Steven, Slash and Duff?

Izzy: Yes, I spoke to them on the phone three days ago, I even have lunch
with Steven last week. He is clean now but physically and mentally...
Slash is well, so is Duff: he just did the Hawaiian marathon! A fucking
marathon. Not bad for a guy whose pancreas exploded because he was drinking
3 1/2 liters of vodka every day? He is my band by the way, that is very
cool. The only who doesn't speak to anybody is Axl. He doesn't call the
people back on the phone. I like to ride my bike and I know where he
lives. Once in 1995, I went there and ring the door bell, he opened the
door, we took each other in our arms, he made me visit his house and we
had a chat. Cool. We called back each other after that, but one day the
old Axl was back; He was taking notes on the phone of what I was telling
him, and then, no news. Since then I go to his place, that makes me laugh:
I ring the door bell and there is always a bouncer telling me he is not
there! I am happy anyway that he did two gigs in Vegas and Rio in the
beginning of the year. I am especially happy that his microphone did work
properly. Who knows, He might have left the stage (he laughs).
