Since Fogelberg's tribute album has been in the works for many years, it's very possible that Glenn did have some input to it before he died.
I was initially expecting Joe and the Eagles to offer two separate tracks to the CD. After Glenn's death, I read a guest list that included Walsh and Henley contributions so I'm disappointed that there is actually just the single Eagles track. The confirmed track list suggests that they've added Don and Tim's backing vocals to the Walsh track and labelled it as the Eagles. I wonder who's playing drums and bass?
I'm pretty sure that there are a number of tracks on
Long Road Out of Eden that don't feature all of Glenn, Don, Tim and Joe so
Part Of The Plan may not be setting that precedent but I don't recall the Eagles recording a cover for a tribute/benefit album before, so I'm kinda pleased at that. it does have a suggestion of testing the water for further Eagles releases in the future, though.
I still look to Irving, Don, Joe and Tim, rather than disenchanted fans, to judge the authenticity of the Eagles and why is this discussion relegated to the "Tour Talk" thread
