I mentioned this before in the 'Eagles Mentions in TV Shows' thread. Here's the page on that thread where I mentioned it:

No need to really look at it though, since I pretty much said the same thing as you.
I watched the music episode for "The Nineties" in the hope that maybe "Hell Freezes Over" and/or "The Dance" would be mentioned to indicate the resurgence of 70's groups coming back to life to become popular and mainstays in the live music circuit once again. But nope, no mention of the Eagles nor Fleetwood Mac. It was about the new music at the time: grunge, country (Dixie Chicks/Garth Brooks/Reba/etc), Alanis Morissette, and Hip Hop/Rap.
I don't remember what the music episode for "The Eighties" had, but I'm pretty sure that Don Henley wasn't mentioned b/c I probably would have said something if he were.
Also, the mention of Fleetwood Mac in "The Seventies" informed me that the person who sings "Go Your Own Way" was not a woman as I've thought, but it was a man, Lindsey Buckingham. Yep, I always thought the song was from a woman until I saw that bearded dude with an afro playing on a white Les Paul. And because of that, I've been on a Fleetwood Mac and Lindsey Buckingham kick for about a year.
