Which Fleetwood Mac album was the last to feature Peter Green?

Then Play On was the last Fleetwood Mac album to feature Peter Green. Released in September 1969, it captured the band's original blues-rock lineup expanding into a more varied and adventurous sound before Green's departure in 1970.

The album was Fleetwood Mac's third studio album and the first of its original albums to feature guitarist Danny Kirwan. Green remained the central guitarist, singer, and songwriter, contributing to songs such as “Coming Your Way,” “Oh Well,” and “The Green Manalishi,” depending on the edition and track listing.

Then Play On moved beyond the straightforward electric blues of the band's first two albums. Its music included elements of folk rock, psychedelic rock, hard rock, and extended instrumental interplay. The album's changing editions can cause confusion because later releases added or removed tracks, including successful singles associated with the period.

Peter Green officially left Fleetwood Mac in 1970 after the European tour that included the band's final performance with him on May 20. Kiln House followed in 1970 without Green, making Then Play On the clear endpoint of his album appearances with the group.
