Stage Select has an excerpt from a rambling chat session between Axl Rose and some fans on the mygnrforum.com touching on a number of topics. The point of interest here is his perspective on the participation of former Guns N Roses guitarist Slash in Guitar Hero III and the game's use of Welcome to the Jungle, which he implies may not have been properly sorted out as far as licensing goes. Here's the somewhat disjointed comment:

"It doesn’t bother me unless it’s being done at my expense and or to keep him associated as in Guitar Hero. Him being Guitar Hero’s fine but not when Activison in using Jungle, having Yahoo use Sweet Child unauthorized, claims no involvement with Slash, his or anyone’s image or VR or anyone or anyone’s music in either camp in promotion or commercials etc. I wasn’t broadsided. I read about it as it moved along but Activision continually denied it right up to the release. That’s some low life chicanery on all their parts.

Yes Slash was in Guns and on Jungle (and the whole I came to him for his riff is as much crap as him saying he brought Locomotive and Coma in as complete songs) and he has rights to perform it but not to be represented in this context in association with Guns. And since they weren’t granted the license it’ll take some sorting.

Universal has Guns under contract but I own the name.

I don’t have problems with whoever doing the songs but film or video gets into sync rights and I don’t have an interest in anyone new, old or whatever trying to sell themselves as GNR under another name that way."
