The rock band previously said they would never perform together again following the shock death of Glenn Frey in January 2016, but they have since performed a U-turn and are now preparing to reunite for the Classic West and Classic East bash later this year.
A source explained: “The Eagles are getting back together on stage.”
“It’s not a decision they have taken lightly but their feelings have changed and they know there’s huge demand from fans who want to see them.
“None of them need the money, they want to make sure the shows are respectful and fitting tribute.”
The Eagles are also still to decide whether they will hire a new singer to replace Glenn.
The insider added: “The band are still dealing with the issue of replacing Glenn and have secretly held talks with some performers, but they are also discussing the possibility of sharing his duties between them.”
The Eagles, whose best-selling hits included ‘Hotel California’ and ‘Take It Easy’ are expected to earn more than $4 million for the shows.
But band member Don Henley previously insisted they would not reunite after they performed ‘Take It Easy’ at the Grammys in February 2016.
He said: “It was very difficult and very emotional. We actually almost didn’t do it.
“That was the final farewell. I don’t think you’ll see us performing again. I think that was probably it. I think it was an appropriate farewell.”
