Well, the set list has certainly changed over the years, but I think that is a good thing. The Farewell 1 set list includes some new songs as well as old favourite classics. HFO was a more experimental set list - look at the acoustic version of Hotel California for instance, and the use of the orchestra on New York Minute. That for me is one of the great attractions of the Eagles, that they can reproduce the sounds of their biggest hits live, but are also prepared to include less well known tracks, particularly ones from their solo albums. I expect they have also had to tailor the selection of songs as their voices have changed. I wish I could hear them do Seven Bridges Road live once more, though!
