Please answer the following question: Information:  - Glam rock (also known as glitter rock) is a style of rock and pop music that developed in the United Kingdom in the early 1970s performed by musicians who wore outrageous costumes, makeup, and hairstyles, particularly platform shoes and glitter. Glam artists drew on diverse sources ranging from bubblegum pop and '50s rock and roll to cabaret theatrics, science fiction, and complex art rock. The flamboyant clothing and visual styles of performers were often camp or androgynous, and have been described as playing with nontraditional gender roles.  - Strawbs (or The Strawbs) are an English rock band founded in 1964. Although the band started out as a bluegrass group they eventually moved on to other styles such as folk rock, progressive rock, and (briefly) glam rock.  - Hounslow is the principal town in the London Borough of Hounslow in Greater London and is part of the historic county of Middlesex. It is a suburban district 10.6 miles (17 km) west south-west of Charing Cross. It forms a larger post town in the TW postcode area and is an economic hub within the capital; it has a large shopping centre which adjoins its high street and a large number of restaurants, cafés and small businesses, many of which are associated with product assembly, marketing, telecommunications and London Heathrow Airport. A minority of its workers are employed in Central London, to which the town is connected by rail and tube. Hounslow is part of the TW3 postcode area, though some areas to the west are in TW4 instead. The population of the town, comprising the Hounslow Central, Hounslow Heath and Hounslow South wards, was 41,304 in the 2011 census.  - Progressive rock (shortened as "prog"; sometimes "art rock", "classical rock" or "symphonic rock") is a broad subgenre of rock music that developed in the United Kingdom and United States throughout the mid to late 1960s. Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing.  - Richard Christopher "Rick" Wakeman (born 18 May 1949) is an English keyboardist, songwriter, television and radio presenter, and author. He is best known for being in the progressive rock band Yes across five tenures between 1971 and 2004 and for his solo albums released in the 1970s.  - Grave New World is a studio album by English band Strawbs . It was the first album to be released after the departure of Rick Wakeman , under circumstances about which band leader Dave Cousins was very bitter . Cousins has admitted that the track `` Tomorrow '' was written about Wakeman . Happily their friendship survived and the two have since performed and recorded together , releasing an album Hummingbird in 2002 . Wakeman 's departure to join prog - rockers Yes caused a lot of predictions of Strawbs demise . Cousins was into the I Ching at the time and he asked the book what he should do . The answer was used in the lyrics for the first track on the album , `` Benedictus '' . Blue Weaver , late of Amen Corner , was recruited and considered by most fans to be a more than adequate replacement for Wakeman . The album depicts the story of one man 's life . For instance , the track `` Hey Little Man '' represents an older man giving advice to his young son . The songs themselves show the continuation of the movement away from Strawbs ' original folk leanings . Founding member Tony Hooper began to be increasingly uncomfortable with this and left after the recording sessions of this album . The original vinyl album had lavish artwork and included a pamphlet showing the lyrics of each track together with details of instrumentation . The front cover is a reproduction of William Blake 's Glad Day . The album reached number 11 in the UK Album Charts .  - Folk rock is a musical genre combining elements of folk music and rock music. In its earliest and narrowest sense, the term referred to a genre that arose in the United States and the United Kingdom around the mid-1960s. The genre was pioneered by the Los Angeles band the Byrds, who began playing traditional folk music and songs by Bob Dylan with rock instrumentation. The term "folk rock" was coined by the U.S. music press to describe the Byrds' music in June 1965, the month in which the band's debut album was issued.  - Dave Cousins (born David Joseph Hindson, 7 January 1945, Hounslow, Middlesex, England) is an English singer and songwriter, who has been the leader, singer and most active songwriter of Strawbs since 1967.  - A songwriter is an individual who writes the lyrics, melodies and chord progressions for songs, typically for a popular music genre such as rock or country music. A songwriter can also be called a composer, although the latter term tends to be used mainly for individuals from the classical music genre. The pressure from the music industry to produce popular hits means that songwriting is often an activity for which the tasks are distributed between a number of people. For example, a songwriter who excels at writing lyrics might be paired with a songwriter with a gift for creating original melodies. Pop songs may be written by group members from the band or by staff writers  songwriters directly employed by music publishers. Some songwriters serve as their own music publishers, while others have outside publishers.    What is the relationship between 'grave new world' and 'folk rock'?
