Question: What year did the Beatles move to Apple Studios?
About the article "Let It Be", section "Recording sessions".

Candidate passages:
This quiet song required 67 takes, and George Harrison did not play (during "The Beatles" sessions, the Beatles often recorded in separate studios).
During take 19 of "I Will", McCartney ad-libbed an untitled and uncopyrighted song (referred to as "Can you take me back?"
by author Ian MacDonald), a 28-second segment of which ended up on side 4 of the album "The Beatles" as what MacDonald described as “a sinister introduction to "Revolution 9"”.
Also ad-libbed by McCartney was "Los Paranoias", released, together with take 1 of "I Will", in 1996 on "Anthology 3".
The picture shown above features Apple Records' 45 rpm record.
It was manufactured by Dyna Products Inc (today's Dyna Music Entertainment Corporation) of the Philippines, 1968. 
Apple Corps Ltd (informally known as Apple) is a multi-armed multimedia corporation founded in London in January 1968 by the members of the Beatles to replace their earlier company (Beatles Ltd) and to form a conglomerate.
Its name (pronounced "apple core") is a pun.
Its chief division is Apple Records, which was launched in the same year.
Other divisions included Apple Electronics, Apple Films, Apple Publishing and Apple Retail, whose most notable venture was the ill-fated Apple Boutique, on the corner of Baker Street and Paddington Street in central London.
Apple's headquarters in the late 1960s was at the upper floors of 94 Baker Street, after that at 95 Wigmore Street, and subsequently at 3 Savile Row.
The latter address was also known as the Apple Building, which was home to the Apple Studio.
From 1970 to 2007, Apple's chief executive was former Beatles road manager Neil Aspinall, although he did not officially bear that title until Allen Klein had left the company.
The current CEO is Jeff Jones.
In 2010, Apple Corps ranked number 2 on the "Fast Company" magazine's list of the world's most innovative companies in the music industry, thanks to the release of "" video game and the remastering of the Beatles' catalogue. 
It was written by McCartney during the Beatles' stay in India, and originally recorded during the 1969 sessions for what would become The Beatles' "Let It Be" album.
Several versions exist, all of which are acoustic, some of them including electric guitar or improvised harmony vocals by McCartney and John Lennon.
According to Paul McCartney in the documentary "Wingspan", he wrote this song for the Beatles' "Let It Be" sessions, but due to tension in the group at the time nobody had the patience to work with it.
Still, the Beatles recorded the song 6 times in January 1969, at their Apple Studios in London.
A composite version made of two of these recordings was released in 1996 on the "Anthology 3" album. 
"All Together Now" recounts how the "Love" project came into being, borne from the personal friendship between George Harrison and Cirque du Soleil founder Guy Laliberte.
George saw how the twin talents of Cirque’s artistry and The Beatles’ music could be fused into something new and totally original.
The title of the DVD refers to The Beatles song "All Together Now".
The director, Adrian Wills, records early meetings between the Cirque & Apple Corps' creative teams, as well as contributions from Sir Paul McCartney, Ringo Starr, Yoko Ono Lennon and Olivia Harrison discussing how The Beatles' music can be used in a different way.
The film touches on the decision to utilize the combined talents of Sir George Martin and his son Giles Martin to produce what became a 90-minute soundscape created from The Beatles' multi-track recordings and how this new audio adventure was being quietly worked on in the famous Abbey Road Studios in London, England whilst the first creative ideas for the show were being formulated in Montreal, Canada.
These early stages of the project were all filmed, as were the first rehearsals in the theatre of The Mirage in Las Vegas, which was completely rebuilt with a one-of-a-kind sound system and complex round staging to house the "Love" show.
George and Giles Martin, the show’s musical directors, were involved with the Cirque du Soleil creative team, performers and backroom staff.
The DVD was released on 20 October 2008.
The DVD won the Grammy Award for Best Long Form Music Video, in 2009, for the director, Adrian Wills, and the producers, Martin Bolduc and Jonathan Clyde.
The Beatles did not receive the award as they did not perform in the video.
They did however receive an award in the same category several years earlier for the Beatles Anthology Video release. 
In 1978, Aspinall instigated the first of three lawsuits on behalf of Apple Corps against Apple Computer, Inc. (now known as Apple, Inc.) for trademark infringement.
The first suit settled in 1981 with an amount of £41,000 being paid to Apple by Apple Computer.
As a condition of the settlement, Apple Computer was allowed to use its logo as long as it did not enter the music business.
The second suit with Apple Computer arose in 1989, when Apple Corps sued Apple Computer over its Apple IIGS (which included a professional synthesiser chip) claiming violation of the 1981 settlement agreement.
In 1991, a settlement of £13.5 million was reached.
McCartney praised Aspinall for trademarking the Apple name worldwide, and called Aspinall "Mr. X" in the Apple Corps organisation.
In September 2003, Apple Computer, Inc. was again sued by Apple Corps, this time for the introduction of the iTunes Music Store and the iPod, which Aspinall and Apple Corps believed was a violation of the previous agreement for Apple Computer to not distribute music.
The trial began on 27 March 2006 in the UK, and ended on 8 May 2006 in a victory for Apple Computer; the judge ruled the company's iTunes Music Store did not infringe on the trademark of Apple Corps.
Aspinall was also involved in several court cases in which Apple Corps took action against EMI:In the early 1990s, Aspinall became the executive producer for "The Beatles Anthology"; he, producer George Martin, and press officer Derek Taylor are the only non-Beatles seen in new footage for the documentary.
He continued to advise the surviving Beatles, as well as Lennon's and Harrison's estates, and to supervise the marketing of music, music videos, and merchandising.
On 10 April 2007, it was announced by Apple that Aspinall had "decided to move on" and Jeff Jones—a longtime VP at Sony Legacy—was hired as CEO to oversee the back-catalogue.
One of Aspinall's final tasks at Apple was to oversee the remastering of The Beatles' back-catalogue for an anticipated 2008 release.
