The Who are an English rock band formed in 1964 by Roger Daltrey (lead vocals, harmonica and guitar), Pete Townshend (guitar, keyboards and vocals), John Entwistle (bass guitar, brass and vocals) and Keith Moon (drums and percussion). They became known for energetic live performances which often included instrument destruction. The Who have sold about 100 million records, and have charted 27 top forty singles in the United Kingdom and United States, as well as 17 top ten albums, with 18 Gold, 12 Platinum and 5 Multi-Platinum album awards in the United States alone.

The Who rose to fame in the UK with a series of top ten hit singles, boosted in part by pirate radio stations such as Radio Caroline, beginning in January 1965 with "I Can't Explain". The albums My Generation (1965), A Quick One (1966) and The Who Sell Out (1967) followed, with the first two reaching the UK top five. They first hit the US Top 40 in 1967 with "Happy Jack" and hit the top ten later that year with "I Can See for Miles". Their fame grew with memorable performances at the Monterey Pop,Woodstock and Isle of Wight music festivals. The 1969 release of Tommy was the first in a series of top ten albums in the US, followed by Live at Leeds (1970), Who's Next (1971), Quadrophenia (1973), The Who by Numbers (1975), Who Are You (1978) and The Kids Are Alright (1979).

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
