28. Guns N' Roses (2012)
Guns N' Roses fans had been counting to down the group's induction into the Rock and Roll Hall of Fame for years prior to their 2012 induction. It seemed like the one chance when Axl Rose might possibly consider maybe playing again with the old lineup. They should have known better. After a long back and forth, Axl finally bailed on the entire ceremony via a long and crazy letter. "I strongly request that I not be inducted in absentia," he wrote, "and please know that no one is authorized nor may anyone be permitted to accept any induction for me or speak on my behalf." Guitarist Izzy Stradlin didn't come either, but that didn't stop Steven Adler, Duff McKagan, Slash, Matt Sorum, Gilby Clarke and Myles Kennedy from playing together. At the time, a reunion between Axl and Slash seemed impossible, but just four years later it happened.
