During the final two years of the Beatles, Lennon and Ono created and attended public [[protests against the Vietnam War]]. They collaborated on a series of avant-garde recordings, beginning in 1968 with ''[[Unfinished Music No.1: Two Virgins]]'', which notoriously featured an unretouched image of the two artists nude on the front cover. The same year, the couple contributed an experimental [[sound collage]] to The Beatles' self-titled "[[The Beatles (album)|White Album]]" called "[[Revolution 9]]", with Ono contributing additional vocals to "[[Birthday (Beatles song)|Birthday]]",<ref>{{cite magazine|last=Gibron|first=Bill|date=December 21, 1968|title=An in-depth Look at the Songs on Side-Three|url=http://www.thewhitealbumproject.com/songs/side-three/|url-status=dead|archive-url=https://web.archive.org/web/20140113003559/http://www.thewhitealbumproject.com/songs/side-three/|archive-date=January 13, 2014|access-date=February 1, 2014|magazine=[[Rolling Stone]]|publisher=The White Album Project}}</ref> and one lead vocal line on "[[The Continuing Story of Bungalow Bill]]", marking the only occasion in a Beatles recording in which a woman sings lead vocals.<ref>Lewisohn, Mark, 2000, ''The Complete Beatles Chronicle'', London: Hamlyn, {{ISBN|978-0-600-60033-6}}, p. 284</ref>

On March 20, 1969, Lennon and Ono were married at the registry office in [[Gibraltar]] and spent their honeymoon in [[Amsterdam]], campaigning with a week-long [[bed-in]] for peace. They planned another bed-in in the US, but were denied entry to the country.<ref>Kruse, Robert J.

Lennon detailed this period in the Beatles' song "[[The Ballad of John and Yoko]]".<ref>Coleman, Ray, ''Lennon: The Definitive Biography'', 1992, p. 550</ref>

During the Amsterdam Bed In press conference, Yoko also earned controversy in the Jewish community for saying during the press conference that, "If I was a Jewish girl in [[Adolf Hitler|Hitler]]'s day, I would approach him and become his girlfriend. After 10 days in bed, he would come to my way of thinking. This world needs communication. And making love is a great way of communicating."<ref name=sexnotcoolhere>{{cite web|url=http://jewishweek.timesofisrael.com/yoko-ono-if-only-hitler-had-sex-with-jewish-women/|title=Yoko Ono: If Only Hitler Had Sex With Jewish Women|first=Jonathan|last=Mark|website=The Times of Israel|access-date=October 5, 2019|archive-date=July 7, 2019|archive-url=https://web.archive.org/web/20190707222206/https://jewishweek.timesofisrael.com/yoko-ono-if-only-hitler-had-sex-with-jewish-women/|url-status=dead}}</ref>

Lennon changed his name by [[deed poll]] on April 22, 1969, switching out ''Winston'' for ''Ono'' as a middle name. Although he used the name John Ono Lennon after that, official documents referred to him as John Winston Ono Lennon.<ref>Coleman, Ray, ''Lennon: The Definitive Biography'', 1984b, p. 64</ref> The couple settled at [[Tittenhurst Park]] at [[Sunninghill, Berkshire]], in southeast England.<ref name="PNorman">Norman, Philip, John Lennon The Life, Hammersmith, England: Harper Collins, 2008, {{ISBN|978-0-00-719741-5}}, p. 615 et seq</ref> When Ono was injured in a car crash, Lennon arranged for a king-sized bed to be brought to the recording studio as he worked on the Beatles' last recorded album, ''[[Abbey Road]]''.<ref>Emerick, Massey, 2006, pp. 279–80</ref>
