Friday 25 October 1968 | Stereo mixing and editing | EMI Studios, Abbey Road, London
On 25 October 1968, George Martin and Geoff Emerick worked on stereo mixing and editing of Martin’s Yellow Submarine orchestral score at EMI Studios. This was the second of two consecutive days preparing the newly recorded score for the soundtrack album.
The previous day’s work is covered in our 24 October Yellow Submarine score article. Together, the two dates form a production sequence following orchestral recording on 22 and 23 October.
The central distinction is between the music heard in the film and the later album recordings. The October sessions did not create the film’s original score performances: those had already been recorded at Olympic Sound Studios.

The film score and the album score were different recordings
The orchestral music used in the film had originally been recorded at Olympic Sound Studios. Martin then chose to re-record the score for the album at Abbey Road.
The distinction concerns the performances captured on tape, not merely a change of packaging. An album version of a film score can share its musical identity with the screen work while drawing on a later recording.
By the time of the October re-recordings, the film had already been released. These sessions therefore belong to the preparation of the album rather than to an attempt to finish the film before its premiere.
The exact dates of the earlier Olympic score sessions are not established in the account used here. They should not be assigned the October Abbey Road dates simply because both sets of recordings concern the same score.
What had been recorded on 22 and 23 October?
Martin conducted a 41-piece orchestra in Studio One at EMI Studios over two recording dates. Those orchestral performances supplied the material being mixed and edited on 24 and 25 October.
The recording sessions were co-produced by Martin, Ron Richards and John Burgess, with Geoff Emerick engineering. Those recording-day credits should be distinguished from the shorter producer-and-engineer listing for the 25 October mixing session.
Likewise, Studio One is documented for the orchestral re-recordings. The dated mixing account identifies EMI Studios but does not establish a specific mixing room, so this article does not invent one.
George Martin’s role in Yellow Submarine
George Martin is central to this entry as the composer and conductor of the orchestral score, as well as its producer. The session is not simply another date on which the Beatles recorded a song bearing the film’s title.
The original soundtrack album brought together Beatles songs and orchestral material. The score’s preparation needs its own account because its recording personnel, musical function and production sequence differ from those of the band’s song recordings.
That separation also avoids a misleading attendance claim. The presence of the Beatles’ name on the album does not establish that all four members were at EMI Studios for this mixing work.
What happened during stereo mixing and editing?
The production team worked with the newly recorded orchestral material to prepare the album presentation. Mixing combined the recorded elements into stereo, while editing shaped the material into its release form.
The two processes are related but not identical. Recording captured the performances; mixing and editing prepared how those performances would be heard on the record.
The surviving dated summary groups the work across 24 and 25 October. It does not provide a reliable minute-by-minute allocation of individual score pieces to this Friday, so a detailed cue timetable is not invented here.
Why the mono LP was not a separate dedicated mix
The original mono album was a fold-down of the stereo mix. In practical terms, the stereo channels were combined for mono rather than the material receiving a wholly separate dedicated mono mix.
This distinction matters when comparing release formats. A mono label does not by itself prove a separate creative mixing session for every album in the catalogue.
Nor should this album’s production history be generalised to every Beatles mono release. The fold-down description applies here to the original Yellow Submarine album under discussion.
From mixing to disc cutting
The later disc-cutting dates were 22 November 1968 for stereo and 25 November for mono, with Harry Moss carrying out the work at Abbey Road.
Cutting is a further stage in preparing a physical record. Those November dates are not alternative dates for the October orchestral performances or for the two mixing sessions.
Keeping the stages separate gives a clearer production timeline:
- Earlier Olympic Sound Studios sessions supplied the film’s original orchestral recordings.
- 22–23 October 1968: the score was re-recorded for the album at EMI Studios.
- 24–25 October: stereo mixing and editing prepared those album recordings.
- 22 November: the stereo album was cut by Harry Moss.
- 25 November: the mono album was cut by Harry Moss.
