Lindsey Buckingham Leaves Fleetwood Mac – Variety: "Lindsey Buckingham, guitarist and songwriter extraordinaire, has left the group Fleetwood Mac, Variety has confirmed. Buckingham has been a key member of Fleetwood Mac, playing with the band from from 1975 to 1987, then, after a decade-long break, returning to the fold in 1997. Fleetwood Mac was inducted into the Rock and Roll Hall of Fame a year later.
News of the exit was first shared by guitarist Billy Burnette, who tweeted on April 4, “Breaking news: Lindsey Buckingham is out but I’m not in.” The message was deleted a few hours after posting. Presumably, Burnette, who replaced Buckingham in the group from 1987 until it went on hiatus in 1995, was angling for a position in the band.
According to a source, Buckingham did not exit voluntarily, rather, says the insider, “He was fired.”"
