Rock band Fleetwood Mac and their member Lindsey Buckingham are cutting ties. The band confirmed that Buckingham and the band have parted ways and that he will not be going on tour with them in the fall. A source close to the band said that the split was "over musical differences regarding the tour." Buckingham joined Fleetwood Mac in 1974, the same year as the band's longtime lead singer, Stevie Nicks.
