The session began at 7pm and finished at 12.45am. The Beatles intended to record a remake of the song, but after one attempt - numbered take 1, despite the previous three - they decided the results of the earlier session were adequate.
Take two from the Regent Sound tape was then subjected to a reduction mix to free up space. This became known as take three, even though a take with that number already existed. The mix combined the lead guitar and backing vocals.
Fixing A Hole was then mixed in mono. Five were made, numbered 2-6, even though there had been no previous mix numbered one.
The final version of the song was an edit of mixes three and six. This was made at the end of the session, and can be heard at the 2'06 mark on the album.
