The Beatles were an English rock band formed in Liverpool in 1960 and one of the most commercially successful and critically acclaimed acts in the history of popular music. The group's best-known lineup consisted of John Lennon (rhythm guitar, vocals), Paul McCartney (bass guitar, vocals), George Harrison (lead guitar, vocals) and Ringo Starr (drums, vocals). Rooted in skiffle and 1950s rock and roll, the group later worked in many genres ranging from pop ballads to psychedelic rock, often incorporating classical and other elements in innovative ways. Their enormous popularity first emerged as "Beatlemania"; as their songwriting grew in sophistication, by the late 1960s they came to be perceived by many fans and cultural observers as an embodiment of the ideals shared by the era's sociocultural revolutions.

John Cameron Fogerty (born May 28, 1945) is an American musician, songwriter, and guitarist, best known for his time with the swamp rock/roots rock band Creedence Clearwater Revival (CCR) and as a solo recording artist. Fogerty has a rare distinction of being named on Rolling Stone magazine's list of 100 Greatest Guitarists at #40 and the list of 100 Greatest Singers at #72. The songs "Proud Mary" and "Born on the Bayou" also rank amongst the Greatest Pop songs ("Proud Mary," #41) and Guitar songs ("Born on the Bayou," #53).

Fogerty was born in Berkeley, California and is the younger brother of the late Tom Fogerty. He attended El Cerrito High School along with the other members of CCR and took guitar lessons from Berkeley Folk Festival creator/producer Barry Olivier.

Inspired by rock and roll pioneers, especially Little Richard and Bo Diddley, John and his brother Tom Fogerty joined Doug Clifford and Stu Cook in the late 1950s to form the band Tommy Fogerty and the Blue Velvets in El Cerrito, California. After signing with the jazz label Fantasy in 1965, they became The Golliwogs and released a few singles that were largely ignored.

Elvis Costello (born Declan Patrick MacManus, 25 August 1954) is an English singer-songwriter. He came to prominence as an early participant in London's pub rock scene in the mid-1970s and later became associated with the punk/New Wave genre. Steeped in word play, the vocabulary of Costello's lyrics is broader than that of most popular songs. His music has drawn on many diverse genres; one critic described him as a "pop encyclopaedia", able to "reinvent the past in his own image".

Costello has won multiple awards in his career, including a Grammy Award, and has twice been nominated for the Brit Award for Best British Male. In 2003, Elvis Costello & the Attractions were inducted into the Rock and Roll Hall of Fame. In 2004, Rolling Stone ranked Costello number 80 on their list of the 100 Greatest Artists of All Time.

Costello was born Declan Patrick MacManus in St Mary's Hospital, London, the son of Lilian Alda (née Ablett, b. 1927, Liverpool) and Ross MacManus (1927–2011), a musician and bandleader. He is of Irish heritage. Costello lived in Twickenham, attending Hounslow Secondary Modern School, which is now St Mark's Catholic Secondary School, in neighbouring Hounslow. With a musically inclined father (who was a jazz trumpeter and sang with The Joe Loss Orchestra), Costello's first broadcast recording was alongside his dad in a television commercial for R. White's Lemonade (I'm a Secret Lemonade Drinker). His father wrote and sang the song; Costello provided backing vocals. The advertisement won a silver award at the 1974 International Advertising Festival.
