on the track. MacDonald characterises the 25–26 May sessions as "chaotic" and typical of the group's drug-inspired efforts after completing their album Sgt. Pepper's Lonely Hearts Club Band late the previous month. On the Sunday following the sessions for "It's All Too Much", the four Beatles attended a party at their manager Brian Epstein's house in Sussex, where Lennon and Harrison introduced music-industry publicist Derek Taylor to LSD. The band returned to De Lane Lea on 2 June, with Martin now participating. That day, the trumpets and bass clarinet parts, played by four session musicians and conducted by Martin, were added to the track. Maginnis describes the opening of the song as "a burst of howling guitar feedback and jubilant, church-like organ", adding: "The atmosphere hints at Harrison's fascination with Indian music and Hindu philosophy at the time, having a distinct, Eastern-flavored, droning undercurrent." Following the intro to "I Feel Fine" in 1964, "It's All Too Much" is a rare example of the Beatles' use of feedback on a recording and suggests the influence of Jimi Hendrix. Womack credits this guitar part to Harrison, who played his Epiphone Casino using "the instrument's Bigsby [tremolo] bar in searing, full vibrato force". Harrison later rued the prominence of the brass accompaniment, saying: "To this day I am still annoyed that I let them mess it up with those damn trumpets. Basically, the song's quite good but, you know, messed up with those trumpets." In the months following the recording sessions, Harrison swore off LSD usage after visiting the Haight-Ashbury district of San Francisco in August, with Boyd, Taylor and others. He said he found himself disillusioned at how, rather than an enlightened micro-society, Haight-Ashbury seemed to be a haven for dropouts and drug addicts. Harrison and Lennon subsequently became avid supporters of Maharishi Mahesh Yogi's Transcendental Meditation technique, after the Beatles had attended a seminar by the Maharishi in Bangor, Wales, in late August. MacDonald writes that, through Harrison's embrace of meditation, "It's All Too Much" served as his "farewell to acid". Mixing The Beatles carried out final mixing on "It's All Too Much", again at De Lane Lea, on 12 October 1967, while completing work on their Magical Mystery Tour EP. They considered the song for inclusion in their 1967 TV film Magical Mystery Tour. Instead, they selected it later that year for the soundtrack to the Yellow Submarine animated film,
