In November 1969, Bunyan returned to England and Boyd organized recording sessions for the subsequent month. Following an extensive day of rehearsals at Sound Techniques, Bunyan completed the entire "Just Another Diamond Day" album during a work-extensive three-day period in December 1969. Bunyan was joined by a wealth of musicians, including John James, Robert Kirby, Robin Williamson of the Incredible String Band, and Dave Swarbrick and Simon Nicol of Fairport Convention. However, Bunyan's diffident approach resulted in her losing control of the songs' arrangements, and only later did she note her reservations toward the album's lack of precision and production. Music historian Richie Unterberger has remarked that despite the multiple influences of outside artists, the drum-less, acoustic arrangements on "Just Another Diamond Day" complemented Bunyan's measured and wispy vocals.
