Working class (or lower class, labouring class, sometimes proletariat) is a term used in the social sciences and in ordinary conversation to describe those employed in lower tier jobs (as measured by skill, education and lower incomes), often extending to those in unemployment or otherwise possessing below-average incomes. Working classes are mainly found in industrialized economies and in urban areas of non-industrialized economies.

As with many terms describing social class, working class is defined and used in many different ways. When used non-academically, it typically refers to a section of society dependent on physical labor, especially when compensated with an hourly wage. Its use in academic discourse is contentious, especially following the decline of manual labor in postindustrial societies. It is often used synonymously for proletariat, particularly amongst Marxist authors. Some academics question the usefulness of the concept of a working class.

The term is usually contrasted with the upper class and middle class, in general terms of access to economic resources, education, cultural interests, and other goods and services. The cut-off between working class and middle class is more specifically where a population spends money primarily as a lifestyle rather than for sustenance (for example, on fashion versus merely nutrition and shelter). Problematically, relying on this method of distinction would rule out many of the people who are often identified as working class.

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.

Monty Python (sometimes known as The Pythons) was a British surreal comedy group who created Monty Python's Flying Circus, a British television comedy sketch show that first aired on the BBC on 5 October 1969. Forty-five episodes were made over four series. The Python phenomenon developed from the television series into something larger in scope and impact, spawning touring stage shows, films, numerous albums, several books and a stage musical as well as launching the members to individual stardom. The group's influence on comedy has been compared to The Beatles' influence on music.

The television series, broadcast by the BBC from 1969 to 1974, was conceived, written and performed by members Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin. Loosely structured as a sketch show, but with an innovative stream-of-consciousness approach (aided by Gilliam's animation), it pushed the boundaries of what was acceptable in style and content. A self-contained comedy team responsible for both writing and performing their work, the Pythons' creative control allowed them to experiment with form and content, discarding rules of television comedy. Their influence on British comedy has been apparent for years, while in North America it has coloured the work of cult performers from the early editions of Saturday Night Live through to more recent absurdist trends in television comedy. "Pythonesque" has entered the English lexicon as a result.
