Errr....no way.
For starters why would Geffen get any money from a G&R tour? Labels have only begun to share touring revenue in recent years, they traditionally front the expense but don't take a huge piece of the gross, especially in a band the caliber of Guns and Roses, regardless of lineup. The label makes revenues from CD sales/Digital downloads/ringtones/new media (video downloads and the like).
The number floating around industry sources was $13 million over a year ago and they pulled the plug on it and told him if he wanted to finish it he would have to come up with the money. Who knows what they worked out to keep the album in progress but that number is unheard of and obscene for a recording budget. Don't forget, that's just the recording cost. A band like G&R would easily have a promotional campaign that runs into the millions, if not the 10's of millions. Radio play, videos and word of mouth cost money. Figure two videos at $2.5 million each, which isn't a lot and another $5-8 mill for promotion and your looking at possibly over $20 Million dollars to recoup before they see a dime of profit. From a cahsflow perspective they're fucked. They're in it up to their assholes with no way out but to keep spending but you better believe they're worried.
