Background: The Jam were an English punk rock and mod revival band active during the late 1970s and early 1980s. They were formed in Woking, Surrey. While they shared the "angry young men" outlook and fast tempos of their punk rock contemporaries, The Jam wore smartly tailored suits rather than ripped clothes, and, rather than rejecting the influences of recent rock history in common with other punk bands, they incorporated a number of mainstream 1960s rock and R&B influences, particularly from The Who, The Kinks and from Motown music. This set the Jam apart from most of their contemporaries, and placed them at the forefront of a nascent mod revival movement.
Context: On 29 April 1977, Polydor released The Jam's debut single, "In the City", which charted in the Top 40 in England. On 20 May, the band released their debut album of the same name. The album, like those of The Clash and the Sex Pistols, featured fast, loud and pointed songs. What set it apart from the records of those two bands was its more prevalent 1960s rock influences. The Jam covered Larry Williams's "Slow Down" (also covered by The Beatles) and the theme song of the 1960s TV series Batman, which was somewhat of a standard for 1960s rock bands. Their originals revealed the influence of Motown Records, The Beatles and The Who.  The Jam had political lyrics, condemning police brutality ("In the City") and expansionist development ("Bricks And Mortar"). However, one of their most openly political songs, "Time For Truth", bemoaned the decline of the British Empire and expressed disparaging sentiments about "Uncle Jimmy" (the Prime Minister, James Callaghan) in no uncertain terms ("Whatever happened to the great Empire?" / "I think it's time for truth, and the truth is you lost, Uncle Jimmy"). These pro-Empire sentiments and ostentatious displays of the Union Flag began to earn the group the tag of "Conservative". Misunderstandings in the music press about The Jam's political or social stance are usually attributed to Weller's lyrical perspective. Even as he pointed out what he saw as wrong and demanded change, Weller's lyrics reflected a deep affection for an idealised vision of England, much in the style of The Kinks' Ray Davies. This contrasted with the Sex Pistols' calls for destruction, or The Clash's calls for revolutionary change.  After the non-LP single "All Around the World" nearly reached the UK Top 10, The Jam, having achieved a notable and loyal following in such a short time, were pressed to produce more material quickly. Their second album, This Is the Modern World, was released later in 1977. Bruce Foxton, generally considered a lesser songwriter than Weller, contributed two songs to the LP ("Don't Tell Them You're Sane" and "London Traffic"), both of which attracted criticism. His composing output gradually decreased, leaving Weller firmly established as the band's chief songwriter. Despite displaying more stylistic variety than before, including some ventures into introspective pop, This Is The Modern World was not widely praised. However, when John Peel first heard the album, he played it in its entirety on one show, one song after the other.
