The Beatles hosted the orchestral session as a 1960s-style happening, with guests including Mick Jagger, Marianne Faithfull, Keith Richards, Brian Jones, Donovan, Pattie Boyd, Michael Nesmith, and members of the psychedelic design collective The Fool. Overseen by Tony Bramwell of NEMS Enterprises, the event was filmed for use in a projected television special that never materialised. Reflecting the Beatles' taste for experimentation and the avant garde, the orchestra players were asked to wear formal dress and then given a costume piece as a contrast with this attire. This resulted in different players wearing anything from fake noses to fake stick-on nipples. Martin recalled that the lead violinist performed wearing a gorilla paw, while a bassoon player placed a balloon on the end of his instrument.
