Spinetti co-authored "In His Own Write", the play adapted from a book by John Lennon with the Beatle which he also directed at the National Theatre, premiering on 18 June 1968, at the Old Vic. Spinetti and Lennon appeared together in June 1968 on BBC2's "Release". During the interview, Spinetti said of the play, that "it's not really John's childhood, it's all of ours really, isn't it John?" to which Lennon replied, assuming a camp voice, "It is, we're all one Victor, we're all one aren't we. I mean 'what's going on?'" Spinetti described the play as being "about the growing up of any of us; the things that helped us to be more aware".
