are." To date, the song is the only US Hot 100 or UK Official Charts single (or #1 single in Australia) in which both the title and the credited act (and also the album and the musical genre) are palindromes. Track listing Personnel Agnetha Fältskog - lead vocals Anni-Frid Lyngstad – backing vocals Björn Ulvaeus – guitar Benny Andersson – keyboards, synthesizer Chart performance Weekly charts Year-end charts Certifications and sales Swedish version by Agnetha Fältskog Agnetha Fältskog's version was the second single from her fifth Swedish solo-album Elva kvinnor i ett hus (Eleven Women in One House). It was the only song from this album not to have been composed by Fältskog herself. Despite the fact that Fältskog never promoted the single in Sweden, it peaked at No. 4 on the singles chart on 1 January 1976 during a 20-week chart run, and it also became Fältskog's third No. 1 on radio chart Svensktoppen, entering the chart on 22 November 1975 and spending a total of eleven weeks on the listing. The B-side of the single, "Visa I Åttonde Månaden" (Song in the Eighth Month) was a song written from a very personal perspective, as it was composed during Fältskog's pregnancy with daughter Linda Ulvaeus in 1973. Cher version American singer Cher's version was the second single from her 2018 album Dancing Queen. It was released on 23 August 2018. The song peaked at number 56 in the Scottish singles chart in August of that year. Critical reception Writing for Rolling Stone, Brittany Spanos felt that "working with producer Mark Taylor who helped seal Cher’s legacy with the game-changing "Believe" in the late Nineties, she finds subtle changes that update ABBA classics without totally stripping them of the catchiness that made those songs beloved hits well beyond their heyday. "Gimme! Gimme! Gimme! (A Man After Midnight)," "SOS" and "Mamma Mia" are given just enough of a knob turn that they're transformed from upbeat FM radio pop into club bangers, pulsating with every beat." Music video An accompanying music video for "SOS" was directed by Jake Wilson, and was premiered through Cher's official YouTube channel on 18 September 2018. The video features Rumer Willis, singer Betty Who, Transparent star Trace Lysette, comedian Sabrina Jalees, Elena of Avalor voice actor Aimee Carrero and Crazy Ex-Girlfriend cast member Vella Lovell.
