So, the picture would be something like:
- John & Yoko move out of Kenwood leaving Lennon's belongings there (=including the Mayoral...)
- John & Yoko go to the hospital on 4 November and Lennon needs a guitar there (=Harrison lends him the Ramírez...)
- John & Yoko returned back to Kenwood and Lennon uses the Ramírez to record some pieces (='Everybody Had A Hard Year', 'Song For John', 'Don't Worry Kyoko'...)
- Harrison recovers his Ramírez (=1969) and Lennon his Mayoral (=1969??)
Why did Lennon prefer nylon instead of -for example- an acoustic guitar to play at the hospital??
