On 29 April 1977, Polydor released the Jam's debut single, "In the City", which charted in the Top 40 in the UK. 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.
