Thanks for posting the link Witchy Woman. Taylor's love of Joe has made me a fan of Taylor. Now I know he loves Barnstorm too, I like him even more. Furthermore, I agree with his comment about the Eagles.
Ignoring the stuff from the last Century (Millennium) The Eagles are a successful touring band. Joe's performance is a large part of that success. That's why they brought him into the band in 1975.
Without Joe, it's debatable whether the Eagles would be able to sell out huge arenas. The audiences are almost unanimously positive about Eagles shows when the shows over b
ut it's not quite so positive after the first set when Joe's been, pretty much on standby. If they can't sell tickets the Eagles wouldn't tour. If the Eagles don't tour they're done.
Taylor didn't question how great the Eagles were/are. He just said they'd be dead without Joe. I'm sure they could make a great album without Joe but these days, they're only interested in selling concert tickets.
IMO the best thing that could happen in 2015 is Joe to re-release Barnstorm with Vitale and Passarelli and tour the world to give it the promotion it deserved in 1972. It's a brilliant, no hits album.
A while ago my brother was dragged to see a big arena show by Take That. He enjoyed the concert. I asked him "What was the highlight of the show?", "The Inflatable Elephant" he answered
That's where I think the Eagles could be heading.
