David "Bruce" Spizer (born July 2, 1955) is a tax attorney in New Orleans, Louisiana, who is also recognized as an expert on The Beatles. He has published eight books, and is frequently quoted as an authority on the history of the band and its recordings.

Spizer was born and raised in New Orleans. He attended Isidore Newman School and then received B.A., M.B.A., and J.D. degrees from Tulane University, where he was a member of honorary societies Phi Beta Kappa and the Order of the Coif. While pursuing his legal career, he also managed The Cold, a popular New Wave band in New Orleans.

In 1997, Spizer earned a large legal fee from the settlement of a class action lawsuit, and decided to use some of the money to replace his childhood collection of Beatles LPs (which had been damaged by cockroaches) with a new set of first edition albums. Drawn into the world of Beatles collectors, he ended up writing and self-publishing The Beatles Records on Vee-Jay, about the relationship between EMI, the Beatles' U.K. record label, and Vee-Jay Records, the U.S. label that released the band's first records in the U.S. As of 2011, Spizer has written and published eight books about The Beatles. A New York Times reviewer described his books as containing "a wealth of detail about the Beatles' American recordings and their first visit to the United States, touching on everything from contracts and lawsuits to promotional materials, all richly illustrated." A New York Daily News article called his The Beatles' Story on Capitol Records "a Beatle collector's fantasy by a fanatic Beatles collector and historian."

Yoko Ono (オノ・ヨーコ（小野 洋子）, Ono Yōko^?, born February 18, 1933) is a Japanese artist, author, and peace activist, known for her work in avant-garde art, music and filmmaking as well as her marriage to John Lennon. Ono brought feminism to the forefront in her music which prefigured New Wave music and is known for her philanthropic contributions to the arts, peace and AIDS outreach programs.

Yoko Ono was born in Tokyo in 1933 to mother Isoko Ono, the great-granddaughter of Zenjiro Yasuda of the Yasuda banking family, and to father Yeisuke Ono, a banker and one-time classical pianist who was a descendant of an Emperor of Japan. The name "Yoko" means "ocean child". Two weeks before she was born, her father was transferred to San Francisco by his employer, the Yokohama Specie Bank. The rest of the family followed soon after and Yoko met her father when she was two. Her younger brother Keisuke was born in December 1936. In 1937, her father was transferred back to Japan and Ono was enrolled at Tokyo's Gakushuin (also known as the Peers School), one of the most exclusive schools in Japan.

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved as a teenager in the skiffle craze; his first band, The Quarrymen, evolved into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.
