Xm channel 30 has been playing an Eagles concert from October. I listened a bit today and they sounded fine.
It's the "Hotel California" channel. It works for me so far, lots of Eagles of course but also each of the band members in their other projects (Joe Walsh with the James Gang

and Timothy B. Schmidt with Poco, for example.) Also lots of "influences". Randy Newman, Jackson Browne, Beatles.
It's only temporary, not sure how long but if it lasts a month or two I'm good with it.
MDS - you're kind of right about how Joe Walsh sounds, like he had a stroke or something. But we listened yesterday for about an hour as he did a show and he was very funny. I like the way he talks even if it's a cross between wasted and brain damaged. How great would it be to sit next to him at a bar for a couple of hours?
Too bad Glen Frey no longer around. They're using Vince Gill and Glen's son a bit to fill in, just not the same. Yes, Gill's as good of a choice as you can get, but he can't help but put that slicked up Nashville voice skill set to to work and though he hits Frey's range great, Glen sang it straight without trying to "country" it all up. Gill is best when he chills a bit and stops acting like he wants another Grammy.
