Editing Anni-Frid Lyngstad (section)

===1985–2004: Later career===
In 1987, Lyngstad was in the choir for the recording of her former husband Benny Andersson's song "''Klinga Mina Klockor''". Also in 1987, Lyngstad recorded the single "''[[Så länge vi har varann|Så Länge Vi Har Varann]]''" ("As Long As We Have Each Other") with the Swedish pop group Ratata, one of Lyngstad's favourites. She was contacted by singer [[Mauro Scocco]], who mentioned that he had a song suitable for a duet. After hearing it, Lyngstad accepted immediately.<ref>Lyngstad herself in ''Frida the DVD''</ref> The song achieved great success in Sweden, and was also recorded in English under the title of "[[Så länge vi har varann|As long as I have you]]". An English-language video of the song was produced, although an Australian release of this song on Festival Records in January 1998 was eventually shelved.

In 1990, Lyngstad became a member of the committee of the Swedish environmental organization ''Det Naturliga Steget'' ("The Natural Step"). The organization wanted a "famous face" to help them reach the public, and in 1991 she became chairwoman for the organization ''Artister För Miljö'' ("Artists for the Environment"). In 1992, Lyngstad founded her Children and Environment Foundation which runs summer camps for underprivileged children.<ref>{{cite web |title=Historik |url=http://barnochmiljo.se/historik.html |access-date=10 February 2021 |website=barnochmiljo.se}}</ref>  Also in 1992, Lyngstad performed live at the [[Stockholm]] Water Festival at the Kings Castle and released the environmental charity single with her cover of [[Julian Lennon]]'s song "Saltwater". All the royalties from this single went to charity. In 1993, on [[Queen Silvia]]'s 50th birthday, Frida was asked to perform "[[Dancing Queen]]" on stage, as performed by ABBA when the king and queen married in 1976. Frida contacted [[The Real Group]] and together they performed the song at the Stockholm Opera House in front of the king and queen. This performance was filmed by Swedish TV and can be seen in ''[[Frida: The DVD]]''.

In 1996, Lyngstad recorded her Swedish language album ''[[Djupa andetag]]'' ("Deep Breaths"). It was a long-awaited album as 12 years had passed since ''[[Shine (Frida album)|Shine]]'' was released. The album attracted overall relatively positive reviews and was a success in Sweden where it reached No. 1 on the album chart. Frida did many TV appearances in Sweden, Norway, Denmark and Finland to promote the album. ''Djupa andetag'' was one of the first Swedish albums to be released as a combined audio-video [[CD-ROM]], including interviews with Lyngstad, footage from the making of the album, as well as promotional videos. Despite the fact that ''Djupa andetag'' was officially only released in Scandinavia and the songs were entirely sung in Swedish, a remix album of the single tracks "''[[Även en blomma]]''", "''Alla Mina Bästa År''" (a duet with [[Roxette]]'s [[Marie Fredriksson]]) and "''[[Ögonen]]''" was released in Germany in 1998, entitled ''[[Frida – The Mixes]]''. Despite the success of the album, none of these singles made a big impression on the Swedish charts. A one-hour documentary about the making of this album, both in the studio and from Frida's home in Mallorca, Spain, can be seen in ''Frida: The DVD''. A follow-up album with producer [[Anders Glenmark]] was reportedly in the works, but was shelved because of the death of Frida's daughter in 1998. Lyngstad dedicated the song "Chemistry Tonight" (co-written by [[Kirsty MacColl]]) to the songwriter after MacColl's death in 2000.

A few low key and one-off recordings followed, including a 2002 duet with opera singer [[Filippa Giordano]] of the "[[Barcarolle]]" from [[Jacques Offenbach]]'s ''[[Les contes d'Hoffman]]'' as well as the song "The Sun Will Shine Again", written by former [[Deep Purple]] member [[Jon Lord]], and recorded in 2004. "Barcarolle" is only available on the Japanese edition of Giordano's album ''Rosso Amore'' and "The Sun Will Shine Again" can be found on Jon Lord's album ''Beyond The Notes'' (although a limited-promotional single had been made available). Lord and Lyngstad made several TV appearances in Germany performing the song, on shows like ''The Sunday Night Classics'' and ''The Golden Henne Gala''. Lyngstad also joined Lord on stage singing the song during his European autumn tour in 2004. During this tour, she also performed "In the Bleak Midwinter", a performance of which can be found on social media.

For the 2004 semi-final of the [[Eurovision Song Contest]], staged in Istanbul thirty years after ABBA had won the contest in Brighton, Lyngstad appeared in a special comedy video made for the interval act, entitled ''Our Last Video''. All four members of the group appeared briefly in cameo roles, as did the singer [[Cher]] and British comedian [[Rik Mayall]] among others. The video was not included in the official DVD release of the Eurovision Contest, but was issued as a separate DVD release on the Universal Music label. It was billed as the first time the four had worked together since the group split in 1982 although they each filmed their appearances separately. Also in 2004, Lyngstad appeared with former bandmates Benny Andersson and Björn Ulvaeus in London at the fifth-anniversary performance of ''[[Mamma Mia! (musical)|Mamma Mia!]]'', the musical based on ABBA songs. In 2008, she joined all three of her former ABBA colleagues at the Swedish premiere of ''Mamma Mia!'' at the arena Cirkus in Stockholm.
