Wondering what was up with Lindsey Buckingham and Stevie Nicks during their performance of "Go Your Own Way" and then reading about their ended relationship later in Rolling Stone. That was probably the most intense performance of a song in concert that I ever witnessed.
I should mention that I was merely five or six feet away from Lindsey and Stevie during that Fleetwood Mac tour for "Rumours".
