and so a song from the recording sessions, "Summer Night City", was released as a single. Never happy with the finished song, members Benny Andersson and Björn Ulvaeus regretted the release and lamented the fact that it peaked lower than previous singles in the charts, not being released at all in the US. They considered the UK to be their most important market, and there it had ended a run of No. 1 hits by stalling at No. 5 - their smallest hit for three years. A full-length version was however still planned for the upcoming album, but ultimately never used. By this time, tensions were growing within the group due to the low productivity of the period, as member Agnetha Faltskog commented; "I can tell from the look in Björn's eyes when he gets home how the day's work has been. Many times the boys have been working for ten hours without coming up with one single note". Andersson talked to a reporter at the time saying; "The prospects are not good. It’s worse than ever...We have no idea when we’ll be finished". It became obvious that the album wouldn't be completed by the end of the year and the deadline was extended into 1979. In late 1978, further indication of internal struggles became widely known when it was announced that married couple Ulvaeus and Faltskog were to divorce. Rather than spelling the end for the group however, this freed up a lot of the tensions between the two and in late 1978, work suddenly took off apace for the album. In October, two tracks were completed: "Angeleyes" and "If It Wasn't for the Nights". Although seen as an archetype ABBA track, the former of these was deemed dated by Andersson, labelling it "back to the sixties". The second track however featured an all-out contemporary vibe, being quite disco-orientated and considered the strongest song that had been recorded for the album. It was intended to be not only the next single but also the song that ABBA would perform at the Music for UNICEF Concert in January 1979. This plan was changed however when an even-better song came along in December. With the original title of "In the Arms of Rosalita", "Chiquitita" was the song the band performed. Although rather more schlager in style, Andersson considered it the best of their new songs, despite the feeling that it was
