It was 45 years ago today (February 4th, 1977) that Fleetwood Mac released their masterpiece, Rumours. To date, the album, which spent 31 non-consecutive weeks on top of the Billboard 200 albums chart, has sold over 40 million copies globally. According to the RIAA’s current list, Rumours is now tied for the eighth best-selling album in history alongside 1977’s Saturday Night Fever soundtrack Shania Twain‘s 1997 collection, Come On Over.

Rumours spawned four Top 10 singles — Lindsey Buckingham‘s “Go Your Own Way,” which hit Number 10; Stevie Nicks‘ “Dreams” — which remains to this day the band’s sole chart-topping single; Christine McVie’s “Don’t Stop,” which peaked at Number Three and “You Make Loving Fun” — which topped out at Number Nine

Recently released are Fleetwood Mac’s expanded and deluxe versions of Rumours. The set has been issued in an “Expanded Edition” featuring the original album, the Stevie Nicks-written B-Side “Silver Springs,” a live collection of tracks from 1977, and a full disc of session outtakes.

The “Deluxe Edition” tags on a second disc of outtakes, a remastered vinyl version of the album, and the vintage concert doc, titled, The Rosebud Film.

Also out now is the book Making Rumours: The Inside Story Of The Classic Fleetwood Mac Album, by the Mac’s legendary co-producer, Ken Calliat. Calliat, who wrote the book with co-author Steve Stiefel, tells the story behind all the 1977 album’s classic tracks — as well as the songs that were bumped from the final lineup.

Making Rumours talks about the creative process, general debauchery, and romantic breakdowns which took place during the 1976 recording sessions between Lindsey Buckingham and Stevie Nicks, John and Christine McVie and Mick Fleetwood and wife Jenny Boyd — the kid sister of Pattie “Layla” Boyd, wife of both George Harrison and Eric Clapton.

In addition to Rumours, Calliat went on to co-produce Fleetwood Mac’s TuskFleetwood Mac Live, and Mirage albums — along with their career-spanning box set, The Chain.
