Some context: ABBA (Swedish pronunciation: [2ab:a]) were a Swedish pop group, formed in Stockholm in 1972 by Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad: the group name derives from the first letter in each of their names. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1982. ABBA won the Eurovision Song Contest 1974 at The Dome in Brighton, UK, giving Sweden its first triumph in the contest. They are the most successful group to have taken part in the competition.
In March 1976, the band released the compilation album Greatest Hits, despite having had only six top 40 hits in the United Kingdom and the United States. Nevertheless, it became their first UK number-one album, and also took ABBA into the Top 50 on the US album charts for the first time, eventually selling more than a million copies there. At the same time, Germany released a compilation named The Very Best of ABBA, also becoming a number-one album there whereas the Greatest Hits compilation followed a few months later to number-two on the German charts, despite all similarities with The Very Best album. Also included on Greatest Hits was a new single, "Fernando", which went to number-one in at least thirteen countries worldwide, including the United Kingdom, Germany and Australia, and the single went on to sell over 10 million copies worldwide. In Australia, the song occupied the top position for 14 weeks (and stayed in the chart for 40 weeks), tying with the Beatles' "Hey Jude" for longest-running number-one, and making "Fernando" one of the best-selling singles of all time in Australia. That same year, the group received its first international prize, with "Fernando" being chosen as the "Best Studio Recording of 1975". In the United States, "Fernando" reached the Top 10 of the Cashbox Top 100 singles chart and number 13 on the Billboard Hot 100. It also topped the Billboard Adult Contemporary chart, ABBA's first American number-one single on any chart.  The group's fourth studio album, Arrival, a number-one best-seller in Europe and Australia, represented a new level of accomplishment in both songwriting and studio work, prompting rave reviews from more rock-oriented UK music weeklies such as Melody Maker and New Musical Express, and mostly appreciative notices from US critics. Hit after hit flowed from Arrival: "Money, Money, Money", another number-one in Germany and Australia, and "Knowing Me, Knowing You", ABBA's sixth consecutive German number-one as well as another UK number-one. The real sensation was "Dancing Queen", not only topping the charts in loyal markets the UK, Germany and Australia, but also reaching number-one in the United States. In South Africa, ABBA had astounding success with "Fernando", "Dancing Queen" and "Knowing Me, Knowing You" being among the top 20 best-selling singles for 1976-77. In 1977, Arrival was nominated for the inaugural BRIT Award in the category "Best International Album of the Year". By this time ABBA were popular in the United Kingdom, most of Western Europe, Australia and New Zealand. In Frida - The DVD, Lyngstad explains how she and Faltskog developed as singers, as ABBA's recordings grew more complex over the years.  The band's popularity in the United States would remain on a comparatively smaller scale, and "Dancing Queen" became the only Billboard Hot 100 number-one single ABBA had there (they did, however, get three more singles to the number-one position on other Billboard charts, including Billboard Adult Contemporary and Hot Dance Club Play). Nevertheless, Arrival finally became a true breakthrough release for ABBA on the US album market where it peaked at number 20 on the Billboard 200 chart and was certified gold by RIAA.

Some context: The Undertones are a punk rock/new wave band formed in Derry, Northern Ireland, in 1974. From 1975 to 1983, the Undertones consisted of Feargal Sharkey (vocals), John O'Neill (rhythm guitar, vocals), Damian O'Neill (lead guitar, vocals), Michael Bradley (bass, vocals) and Billy Doherty (drums). Much of the earlier Undertones material drew influence from punk rock and new wave; the Undertones also incorporated elements of rock, glam rock and post-punk into material released after 1979, before citing soul and Motown as the influence for the material released upon their final album. The Undertones released thirteen singles and four studio albums between 1978 and 1983 before Sharkey announced his intention to leave the band in May 1983, citing musical differences as the reason for the break up.
By 1977 the band were performing their own three-chord pop punk material, which was performed alongside cover versions at concerts, primarily at The Casbah, where the band began to perform in February. The Undertones had occasionally earned money at venues where they had performed throughout 1976, but these gigs at The Casbah were the first performances for which the Undertones were paid on a regular basis, as performing at The Casbah earned the group up to PS40 a week. This inspired the band to write and rehearse further material, as a means of remaining a popular act at this venue. By mid-year, the concerts the Undertones performed would include the song "Teenage Kicks", which had been written by guitarist John O'Neill in mid-1977. The gigs performed at The Casbah gave the Undertones increased confidence in their musical ability, and in June 1977 they performed concerts outside Derry for the first time, supporting a Dublin punk group named The Radiators from Space.  In March 1978, the Undertones recorded a demo tape at Magee University in Derry and sent copies of the tape to various record companies in the hope of securing a record deal, but only received official letters of rejection. The band had also sent a copy of their recordings to influential BBC Radio 1 DJ John Peel, requesting he play the songs on his radio programme. Peel replied to the band, offering to pay for a recording session in Belfast. On 16 June 1978, the band recorded their debut four-song EP "Teenage Kicks" on a budget of only PS200. The EP was engineered by Davy Shannon at Wizard Sound Studios, Belfast - and was released on Belfast's Good Vibrations record label. The title song became a hit with support from John Peel, who considered Teenage Kicks his all-time favourite song, an opinion he held until his death in 2004.  Seymour Stein, the president of Sire Records - in London on business - heard John Peel play "Teenage Kicks" on BBC Radio 1 and became interested in the band. Stein sent a London-based representative named Paul McNally to Derry to discuss a record deal with the band. McNally saw the band play live in what would ultimately prove to be their final performance at The Casbah on 29 September 1978. The following day, McNally convened with the Undertones to discuss a record contract. Three members of the band signed the proposed contract on this date, with the understanding that Feargal Sharkey and Michael Bradley would discuss negotiations to the contract with Seymour Stein in person in London.
