1. The original Fleetwood Mac was led by guitarist Peter Green, who is widely considered to be one of the best English blues guitarists of all time.
2. Founding member Jeremy Spencer abruptly left the group in 1971 to join the Children of God cult.
3. Guitarist Danny Kirwan left the band after a bizarre episode in which he went flipped out while the band was tuning up, ran into a bathroom, and smashed his head against a wall before destroying his guitar.
4. Christine McVie's maiden name was actually Christine Perfect, and she released her first solo album in 1970 under that name.
5. Lindsey Buckingham and Stevie Nicks were recruited to join Fleetwood Mac after Mick Fleetwood visited the Sound City recording studio and asked to hear the most recent album recorded there.
Studio owner Ken Olsen played "Frozen Love," a cut from the duo's debut album, which he had produced.
Fleetwood was blown away by Buckingham's playing and initially only wanted to invite him to join the band, but Buckingham refused to join unless Nicks came with him.
6. The classic lineup of Fleetwood Mac – Fleetwood, Nicks, Buckingham, Christine and John McVie – was actually the 10th lineup of the band.
7. Christine McVie was not impressed with the first draft of Nicks' "Dreams," which went on to become the band's biggest hit.
Here's an early recording of "Dreams" featuring only Nicks' vocal, Buckingham on guitar, and McVie on keyboard.
8. "The Chain" is the only song credited to all five members of the classic lineup of Fleetwood Mac. It was created by merging three distinct songs...
"Lola (My Love)," a Buckingham Nicks outtake penned by Lindsey Buckingham...
...an unfinished track called "Keep Me There," which was written by Christine McVie based on a groove developed by bassist John McVie and drummer Mick Fleetwood...
...and this early acoustic version of "The Chain" by Stevie Nicks which has the same chorus as the final composition, but is otherwise a completely different song.
9. Mick Fleetwood's wife, model Jenny Boyd, was having an affair with his best friend and former Mac guitarist Bob Weston through the mid-'70s.
10. Christine McVie wrote "You Make Loving Fun" about her affair with the band's lighting director, Curry Grant.
11. Stevie Nicks' ballad "Silver Springs" was cut from "Rumours" at the last minute because there was not enough space on the LP and the rest of the band didn't think it fit with the rest of the songs. It was used as the b-side for "Go Your Own Way."
Stevie resented this, and was even more upset when the band kept her from releasing it on one of her solo albums. It eventually became a hit when they re-recorded it for "The Dance" in 1997.
12. When the band decided to drop "Silver Springs," they realized they needed to replace it with another Nicks number. Buckingham chose "I Don't Want To Know," a song they performed together as a duo, without consulting her.
Buckingham recorded this rough version of the song while Nicks was out of the studio.
Nicks was surprised and happy to learn the band had begun work on one of her songs, but was still bitter that "Silver Springs" was being dropped.
