Last month, Guns N’ Roses was inducted into the Rock and Roll Hall of Fame.  While frontman Axl Rose and former guitarist Izzy Stradlin decided not to show up for the induction ceremony, the band’s other original members — guitarist Slash, bassist Duff McKagan and drummer Steven Adler — partnered with ex-guitarist Gilby Clarke and Alter Bridge frontman Myles Kennedy to perform at the event.

In McKagan’s Seattle Weekly blog, which runs every Thursday, the ex-GN’R member says that while Kennedy filled in for Rose, the bass player “devised a plan” for Green Day frontman Billie Joe Armstrong to “sing whatever was needed…if needed” at the event.

McKagan added that the band’s decision to perform was a spontaneous one.  “We really didn’t know if we were going to play at all,” he wrote.  “It wasn’t cemented until we actually rehearsed at 2 a.m. the day of the show.  It was all THAT last-minute.”

The bassist also noted that he had some reservations about performing at the event.  “For Slash and me, it was the first time we’d played our songs with Steven Adler in something like 22 years,” he wrote.  “We had to wonder: Would it work? Would we be able to get our mojo back with only 14 hours to spare before playing in front of an audience of 7,000, and be filmed for an HBO Special!?”

In addition, McKagan wrote that he was “very satisfied about the outcome” of the band’s performance at the event and thanked Clarke and Kennedy “for their heroic, last-minute efforts.”
