Duff McKaganRegrets, Duff McKagan's had a few. Now he admits that last year's onstage reunion with Axl Rose is definitely one of them.

"I almost wish the getting on stage part hadn't happened," the Velvet Revolver musician told Rock News Desk, saying that the live impromptu London jam between the Guns N' Roses co-founders was a mistake because it has refueled fans' hopes for a regrouping of the group's classic lineup.

On a personal level, McKagan said he's happy he ran into Rose when they wound up having hotel suites next to each other. "We were meant to connect again," he said of the chance meeting. "It was a private matter, but I'm glad it happened."
