Its been a bad month to be a guy in your late sixtys. While I love the Eagles with the early years lineup, it's really just been a money machine for Frey and Henley for a couple of decades now (since the reunion and later lineup) - not that I really begrudge them that sort of success. The real Eagles go back to Linda Rondstat's backing band days (Linda is another sad story), when other founding members like Randy Meisner (Bass) was a big part of the band. Meisner wrote "Take it to the Limit" and Bernie Leadon who was responsible for the 'blue grass' sound to much of the early Eagles work.
RIP Glenn Frey, the music will live on.
