Letterman sounded off just four days after Colbert announced 'The Late Show' was coming to an end

The storied album, which the duo released before joining Fleetwood Mac, will be reissued for the first time on Sept. 19 by Rhino High Fidelity, five decades after its original release.

The 1973 album was a commercial disappointment upon release, but has enjoyed a cult legacy ever since, in part thanks to its elusiveness: Buckingham Nicks never received a remaster or reissue after its debut, and thus became largely unavailable for decades. On September 19, that will finally change.
