Background: The Smiths were an English rock band formed in Manchester in 1982. The band consisted of vocalist Morrissey, guitarist Johnny Marr, bassist Andy Rourke and drummer Mike Joyce. Critics have called them one of the most important bands to emerge from the British independent music scene of the 1980s. NME named the Smiths the "most influential artist ever" in a 2002 poll.
Context: In early 1987 the single "Shoplifters of the World Unite" was released and reached number 12 on the UK Singles Chart. It was followed by a second compilation, The World Won't Listen. The title was Morrissey's comment on his frustration with the band's lack of mainstream recognition, although the album reached number two in the charts. This was followed by the single "Sheila Take a Bow", the band's second (and last during the band's lifetime) UK top-10 hit. Another compilation, Louder Than Bombs, was intended for the overseas market and covered much the same material as The World Won't Listen, with the addition of "Sheila Take a Bow" and material from Hatful of Hollow which was yet to be released in the US.  Despite their continued success, tensions emerged within the band to threaten their split. Johnny Marr was exhausted and took a break from the band in June 1987, which he felt was negatively perceived by his bandmates. In July, Marr left the group because he erroneously thought an NME article entitled "Smiths to Split" was planted by Morrissey. That article, written by Danny Kelly, alleged that Morrissey disliked Marr working with other musicians, and that Marr and Morrissey's personal relationship had reached breaking point. Marr contacted NME to explain that he had not left the band due to personal tensions but because he wanted wider musical scope.  Former Easterhouse guitarist Ivor Perry was brought in to replace Marr, and the band recorded some material with him which was never completed, including an early version of "Bengali in Platforms", originally intended as the B-side of "Stop Me If You Think You've Heard This One Before". Perry was uncomfortable with the situation, stating "it was like they wanted another Johnny Marr", and the sessions ended with (according to Perry) "Morrissey running out of the studio". By the time the group's fourth album Strangeways, Here We Come was released in September, the band had split.  The breakdown in the relationship has been primarily attributed to Morrissey's irritation by Marr's work with other artists and Marr growing frustrated by Morrissey's musical inflexibility. Marr particularly hated Morrissey's obsession with covering 1960s pop artists such as Twinkle and Cilla Black. Marr recalled in 1992, "That was the last straw, really. I didn't form a group to perform Cilla Black songs." In a 1989 interview, Morrissey cited the lack of a managerial figure and business problems as reasons for the band's split.  Strangeways, Here We Come peaked at number two in the UK and was their most successful album in the US, reaching number 55 on the Billboard 200. It received a lukewarm reception from critics, but both Morrissey and Marr name it as their favourite Smiths album. A couple of further singles from Strangeways were released with live, session and demo tracks as B-sides. The following year the live recording Rank, recorded in 1986 with Craig Gannon on rhythm guitar, repeated the UK chart success of previous albums.
