12. Eagles (1998)
The Eagles reformed for a crazily lucrative reunion tour four years before they were inducted into the Rock and Roll Hall of Fame, but former members Randy Meisner and Bernie Leadon weren't invited to the party. All seven Eagles came together and played "Take It Easy" and "Hotel California" at the ceremony. Don Felder left the band a few years later and things got really, really ugly. Don Henley can't even say his full name these days (calling him only Mr. Felder), let alone agree to play with him. Bernie Leadon toured with them between 2013 and 2015, and Meisner might have been there if he didn't have health problems. But the death of Glenn Frey means the Eagles are over forever, so this is the only time all seven got to play together.
