It's from a Chicago Tribute article (Aug 9. 1989), an interview with Don Henley. Apparently Don was VERY pissed off that Joe was performing "Life in the Fast Lane" during solo shows. He really lashes out at Joe when asked about it. The pertinent part:
----------------------
"Still, as he begins his own tour in support of The End of the Innocence, his first new album in nearly five years and a current Top 20 hit, at least one of the Eagles is on Henley's mind: Joe Walsh, now touring as part of ex-Beatle Ringo Starr's band. Walsh takes a solo turn in Starr's show performing "Life in the Fast Lane," an Eagles' hit from 1977, and Henley isn't happy about it.
"That's not his song to do," he fumes. "(Eagles founding member) Glenn Frey and I wrote 90 percent of that song, and I sang it on the record. Joe wrote the opening guitar riff." Henley laughs. "Joe had his own solo career before he joined the Eagles, so I don't understand why he doesn't do a song that's more his, instead of doing that one. Besides, he sounds like he's got a clothespin on his nose."
Sounds as if Henley might harbor a certain amount of resentment.
"Right. I also resent some of the things he said in the press when the group broke up," says Henley. "I didn't want to talk about it before, but the hell with that. I don't mind telling you, Joe Walsh was one of the reasons the Eagles broke up. He was instrumental in the disintegration of that group. He was an insidious troublemaker. He would split the band into factions. He was a very divisive presence and very covert about it. He was very hypocritical. Glenn and I used to laugh and say, 'Yeah, Joe's a very interesting bunch of guys.' You can print that, too. I`m tired of being Mr. Nice Guy.
"I'm not going to try to do anything about Joe doing 'Life in the Fast Lane,' though," says Henley. "It would just bring more publicity (to a situation) where there probably shouldn't be any publicity in the first place."
------------------------------
Ouch! I wonder how Don reacted when Joe started doing "Desperado" not long after this...
I extrapolated from Felder's book that one "faction" was Joe, Randy and Felder. Obviously, any faction involving Randy only occurred during the HC period before he left. I don't know how Joe (allegedly) worked out factions during recording of The Long Run. One still included Felder as we can garner from his book, but the use of the plural and the level of bitterness makes me wonder if Don feels Joe also got between him and Glenn. I seriously doubt Tim was involved.
