A recording of this demo may be found on this YouTube video from 8:48-10:56.
A transcription of the full Kenwood demo is below. (Click the picture to enlarge.)
Note: In many instances, the rhythms have been simplified for the sake of visual simplicity.
The next important aspect is that two verses are now complete - both musically and lyrically. The last take had just the first line of the second verse complete. Since then, Lennon finished the lyrics of the second line. All that is now missing is verse 1 ("Living is easy with eyes closed...").
Also, the chorus has been greatly modified - particularly the ending of the chorus, the lyrics of which at last take were "Strawberry Fields and nothing" (which may well be placeholder lyrics until he figured out something better), and is now "Strawberry Fields forever". This is, in fact, the first time the title lyrics are used in the song, and is therefore presumably when Lennon changed the song's name from "It's Not Too Bad" to "Strawberry Fields Forever". These changes would be retained through to the release.
Lastly, the Kenwood demo is the first instance of the coda ("coda" is Italian for "tail" - meaning the end of the song). This, too, would be retained through to the release (though the released version will add a great deal to it).
"Strawberry Fields Forever" was now ready for the recording studio.
