At least one other member of Guns N' Roses' classic-era lineup could be part of the band's long-awaited reunion. Eddie Trunk, the hard-rock radio and TV host, says negotiations are underway for a possible guest role for Steven Adler. Fellow co-founder Izzy [Stradlin] might also sit in, he says.

"My sources have told me current GNR drummer Frank Ferrer will be retained and play the bulk of the show," Trunk wrote on his official website. Adler, Trunk noted, could make an appearance "if a deal can be worked out."

Axl Rose, Slash and Duff McKagan have finally confirmed they will take the stage at Coachella, but made no mention of who will fill out the rest of the lineup – or whether their April stop in Indio, Calif., will lead to more dates down the road. "Strong rumors suggest there will be a couple warm up dates and then more extensive touring after Coachella, if it goes well and the offers are what they expect," Trunk said. "But things are far from cut-and-dry here."

Matt Sorum and Gilby Clarke (who replaced Adler and Stradlin, respectively) will likely not be involved at all, Trunk added. "I would suspect the same with Richard Fortus staying, and maybe Izzy popping up. I would also expect [later-period contributors] Dizzy [Reed] and Chris Pitman to stay."

Also included in the swirl of rumors is Dave Kushner, who played three Guns N' Roses members in Velvet Revolver. Trunk said he doesn't "see the connection, but anything is possible. Axl always liked three guitars in the later-era Guns, so who knows?" Is this three-fifth configuration enough to lure Guns N' Roses' purists back to the fold? "For most, yes; for some, no," Trunk admitted. "But it will do huge business regardless of the percentage that was holding out hope for an Appetite reunion 100 percent. That was never going to happen anyway, since Guns only really made one album with that band."
