Some context: Paul Warfield Tibbets Jr. was born in Quincy, Illinois, on 23 February 1915, the son of Paul Warfield Tibbets Sr. and his wife, Enola Gay Tibbets. When he was five years old the family moved to Davenport, Iowa, and then to Iowa's capital, Des Moines, where he was raised, and where his father became a confections wholesaler. When he was eight, his family moved to Hialeah, Florida, to escape from harsh midwestern winters. As a boy he was very interested in flying.
The 509th Composite Group returned to the United States on 6 November 1945, and was stationed at Roswell Army Airfield, New Mexico. Colonel William H. Blanchard replaced Tibbets as group commander on 22 January 1946, and also became the first commander of the 509th Bombardment Wing, the successor to the 509th Composite Group. Tibbets was a technical advisor to the 1946 Operation Crossroads nuclear tests at Bikini Atoll in the Pacific, but he and his Enola Gay crew were not chosen to drop another atomic bomb.  Tibbets then attended the Air Command and Staff School at Maxwell Air Force Base, Alabama. On graduating in 1947 he was posted to the Directorate of Requirements at Air Force Headquarters at the Pentagon. When the head of the directorate, Brigadier General Thomas S. Power, was posted to London as air attache, he was replaced by Brigadier General Carl Brandt. Brandt appointed Tibbets as director of Directorate of Requirements's Strategic Air Division, which was responsible for drawing up requirements for future bombers. Tibbets was convinced that the bombers of the future would be jet aircraft and thus became involved in the Boeing B-47 Stratojet program. He subsequently served as B-47 project officer at Boeing in Wichita from July 1950 until February 1952. He then became commander of the Proof Test Division at Eglin Air Force Base in Valparaiso, Florida, where flight testing of the B-47 was conducted.  Tibbets returned to Maxwell Air Force Base, where he attended the Air War College. After he graduated in June 1955, he became Director of War Plans at the Allied Air Forces in Central Europe Headquarters at Fontainebleau, France. He left Lucy and his sons behind in Alabama, and he and Lucy divorced that year. During his posting to France, he met a French divorcee named Andrea Quattrehomme, who became his second wife. He returned to the United States in February 1956 to command the 308th Bombardment Wing at Hunter Air Force Base, Georgia, and married her in the base chapel on 4 May 1956. They had a son, James Tibbets.  In January 1958, Tibbets became commander of the 6th Air Division at MacDill Air Force Base, Florida. and was promoted to brigadier general in 1959. This was followed by another tour of duty at the Pentagon as director of Management Analysis. In July 1962, he was assigned to the Joint Chiefs of Staff as deputy director for operations, and then, in June 1963, as deputy director for the National Military Command System. In 1964, Tibbets was named military attache in India. He spent 22 months there on this posting, which ended in June 1966. He retired from the United States Air Force (USAF) on 31 August 1966.

Some context: Yoko Ono (born February 18, 1933) is a Japanese multimedia artist, singer, songwriter, and peace activist who is also known for her work in performance art and filmmaking. She performs in both English and Japanese. She is known for being the second wife and widow of singer-songwriter John Lennon of the Beatles. Ono grew up in Tokyo and also spent several formative years in New York City.
During the last two years that the Beatles performed, Lennon and Ono created and attended their own public protests against the Vietnam War. On March 20, 1969, they 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. They held one instead at the Queen Elizabeth Hotel in Montreal, where they recorded "Give Peace a Chance". Lennon later stated his regrets about feeling "guilty enough to give McCartney credit as co-writer on my first independent single instead of giving it to Yoko, who had actually written it with me." The famous couple often combined advocacy with performance art, such as in "bagism", first introduced during a Vienna press conference, where they satirised prejudice and stereotyping by wearing a bag over their entire bodies. Lennon detailed this period in the Beatles' song "The Ballad of John and Yoko".  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 thereafter, official documents referred to him as John Winston Ono Lennon, since he was not permitted to revoke a name given at birth. The couple settled at Tittenhurst Park at Sunninghill, Berkshire, in southeast England. When Ono was injured in a car accident, 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.  The two artists collaborated on many albums, beginning in 1968 when Lennon was still a Beatle, with Unfinished Music No.1: Two Virgins, an album of experimental musique concrete. The same year, the couple contributed an experimental piece to The White Album called "Revolution 9". Also on The White Album, Ono contributed backing vocals on "Birthday", and one line of lead vocals on "The Continuing Story of Bungalow Bill." The latter marked the only occasion in a Beatles recording in which a woman sings lead vocals.
