Fleetwood Mac are officially reissuing their 1969 album Then Play On - their final LP release with co-founder and guitarist Peter Green.

The band's third album arrived with the addition of Danny Kirwin and before the Buckingham/Stevie Nicks era of the group's history, and it set to be released as a reissue on September 18 via BMG.

Then Play On will contain four bonus tracks, liner notes from the band’s biographer Anthony Bozza, and a foreword from Mick Fleetwood.

The news comes ahead of Mick Fleetwood And Friends Celebrate The Music Of Peter Green, a concert film that gets an international release later this year.

The show took place at The Palladium in London and featured Steven Tyler, Christine McVie and Pink Floyd‘s David Gilmour, among others.

In May, Nicks revealed that she’s been working on a movie inspired by Fleetwood Mac's hit ‘Rhiannon’.
