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.

The Jam formed in Woking, Surrey, England, in 1972. The line-up was fluid at this stage, consisting of Paul Weller on bass and lead vocals together with various friends at Sheerwater Secondary School. They played their first gigs at Michael's, a local club. The line-up began to solidify in the mid-1970s with Weller, guitarist Steve Brookes and drummer Rick Buckler. In their early years, their sets consisted of covers of early American rock and roll songs by the likes of Chuck Berry and Little Richard. They continued in this vein until Weller discovered The Who's debut album My Generation and became fascinated with Mod music and lifestyle. As he said later, "I saw that through becoming a Mod it would give me a base and an angle to write from, and this we eventually did. We went out and bought suits and started playing Motown, Stax and Atlantic covers. I bought a Rickenbacker guitar, a Lambretta GP 150 and tried to style my hair like Steve Marriott's circa '66." Eventually Brookes left the band, and was not replaced. Up to this point Weller had been playing bass and Foxton had been the band's second guitar player; he persuaded Foxton to take over bass duties and developed a combined lead/rhythm guitar style influenced by The Who's Pete Townshend as well as Dr. Feelgood guitarist Wilko Johnson. The line-up of Weller, Foxton, and Buckler would persist until the end of The Jam's career. Throughout, the band were managed by Weller's father, John Weller, who then managed Paul's career until he (John) died in 2009. In the following two years, The Jam gained a small following around London from playing minor gigs, becoming one of the new lights on the nascent punk scene. In many ways, however, they stood out from their punk peers. Though they shared an "angry young men" outlook, short hair, crushing volume and lightning-fast tempos, the Jam wore neatly tailored suits where others wore ripped clothes, played professionally where others were defiantly amateurish, and displayed clear 1960s rock influences where others were disdainful (at least ostensibly) of such music (which had been a major influence on the "stadium rock" and "prog rock" of the 1970s). Indeed, the band were tagged by some journalists as "revivalists". They were signed to Polydor Records by Chris Parry in early 1977.Answer this question using a quote from the following article:
