Duff McKagan's recent concert appearances with the current version of Guns N' Roses have fueled fans' fervor for a full-fledged reunion of the classic lineup, but Slash still isn't feeling nostalgic about his former band.

"I didn't think much about it," he shrugged when the Toronto Sun asked him for his thoughts regarding McKagan mending fences with GNR frontman Axl Rose. "Why would I care? If you remember correctly, Duff was the last guy in the band."

Pressing further, Sun writer Mark Daniell wondered if Slash ever thinks about what might have been if Guns N' Roses had managed to avoid splintering in the early '90s. "I don't think about that because that's not what happened, so what's the point? People are always like, 'What if you had done things differently?' Not only with GNR. But it's just such a waste of time," he argued. "Things happened and it's done. I sort of loathe looking back and fantasizing about anything one way or another, because in the end it didn't happen."

Slash's comments echo earlier remarks regarding McKagan's Guns reunion, which also stressed that even if he isn't interested in following suit himself, he doesn't have any problem with Duff doing it. "I don’t judge Duff. He’s cool," he insisted in April. "He just has a way more amicable, neutral relationship with Axl than I do."

Rather than looking back, would no doubt prefer that fans look forward to his new LP, 'World on Fire,' due Sept. 17. In fact, he's so focused on the new music (which he's warming up for with a series of tour dates with Aerosmith) that he's refused to comment on rumors that he'll be co-starring in a 'Breaking Bad' spinoff series currently seeking funding via Kickstarter. Given that the show's campaign has raised nowhere near its $500,000 goal, it seems awfully unlikely anyway, which is kind of a shame -- as the show's creator put it, "Who doesn't want to see Slash with a Glock sticking out from under that jacket? Come on!"
