So proclaimed Don Henley a few songs into the Eagles opening production at the Sphere in Las Vegas Friday. The “whatever this is” to that point included a video journey through the “Hotel California,” both a lovely and eerie place with a Greek chorus chiming in the background,

The show’s set list offered an array of material from throughout the Eagles’ legendary career. Naturally, there were plenty of classic hits — such as “Heartache Tonight” and “Desperado” — as well as deeper cuts, like “Those Shoes.”
