During this period, Barham met
George Harrison of
the Beatles through Shankar, who had adopted the guitarist as his sitar student. Harrison was fascinated by Barham's interpretations of ragas, and based his 1967 song "
Blue Jay Way" on a piano piece that Barham had derived from
Raga Marwa. In March 1967, Barham attended the recording session for Harrison's Indian-styled composition "
Within You, Without You", released on the Beatles' seminal album ''
Sgt. Pepper's Lonely Hearts Club Band''. Barham later wrote the choral arrangements for
Phil Spector's controversial production of "
The Long and Winding Road" and "
Across the Universe", issued on the band's final album,
Let It Be (1970). Several commentators credit Harrison as the person most responsible for Indian music's surge in popularity in the West from 1966 onwards, via his work with the Beatles and his public endorsement of Shankar. Among these, author Simon Leng has described Barham as both a "birth partner" and the "closest confidant and fellow traveler" to Harrison during the latter's immersion in the genre.
Harrison solo albums Barham played a key collaborative role on Harrison's soundtrack to the
Joe Massot-directed film
Wonderwall (1968). In addition to participating in recording sessions held at London's
Abbey Road Studios in late 1967, it features Barham on piano,
harmonium and
flugelhorn, and in the role of orchestral arranger. Following the Beatles' break-up in April 1970, Barham supplied the orchestral arrangements on Harrison's acclaimed triple album
All Things Must Pass (1970). The album was co-produced by Spector, whose "distant and authoritarian" style Barham says he found difficult to adapt to after the "intimate, friendly atmosphere" typical of Harrison sessions. The songs to which Barham contributed include the international hits "
My Sweet Lord" and "
What Is Life", the album's
title track, and "
Isn't It a Pity". The last of these, Leng writes, "captures the depth of the musical understanding between George Harrison and John Barham", in the interplay between
slide guitar, orchestra and choir. Barham provided the orchestration for Harrison's successful follow-up to
All Things Must Pass,
Living in the Material World (1973).
Other Beatles-related recordings Barham also worked on Harrison's projects with acts signed to the Beatles'
Apple record label. Among these releases was
Is This What You Want? (1969) by
Jackie Lomax, ''
That's the Way God Planned It'' (1969) by
Billy Preston, and
Radha Krishna Temple (London)'s 1970 hit single "
Govinda". The latter was a musical adaptation of a sacred
Hindu poem from the
Satya Yuga. Through his connection with Harrison, Barham also played
harpsichord on
Yoko Ono's "Who Has Seen the Wind?", released in February 1970 as the
B-side to
John Lennon's Spector-produced single "
Instant Karma!" Following the success of
All Things Must Pass, Barham contributed to
Ronnie Spector's "
Try Some, Buy Some" single, Lennon's song "
Jealous Guy" (from
Imagine) and
Gary Wright's album
Footprint, all recorded in 1971. He has said of working with Wright and Harrison that "there was a strong [musical] rapport among the three of us" and describes Wright's song "Love to Survive" as "one of the most emotionally powerful love songs that I have ever worked on". In his book
Phil Spector: Out of His Head, music journalist
Richard Williams writes of Barham's orchestration on "Try Some, Buy Some": "[The strings and mandolins] sweep and soar in great blocks of sound, pirouetting around each other like a
corps de ballet in slow motion. The closing portions of the orchestral arrangement are breathtaking, displaying a geometrical logic which makes use of suspended rhythms drawn out to screaming point." ==Production for Quintessence and
Jugalbandi album==
