This is what we found on Wikipedia regarding the ABBA: Thank You For The Music:

"Thank You for the Music" is a song by the Swedish pop group ABBA, recorded for their fifth studio album The Album (1977). Agnetha Fältskog sang lead vocals. It was originally released on 2 May 1978, as a double a-side single with "Eagle" in limited territories.

The single has gone on to become a fan favorite from the group. As a double A-side single with "Eagle", it cracked the top ten in Belgium, the Netherlands, Switzerland, and West Germany. In South Africa, it was released as a standalone single and peaked at number two on the Springbok Radio chart. In 1980, the single was recorded in Spanish, with lyrics provided by Buddy and Mary McCluskey, as ""Gracias por la Música", and released in Latin America to promote the group's Spanish-language compilation Gracias Por La Música, peaking at number four in Argentina. Later, in November 1983, the song was released in the United Kingdom for the first time, to promote the British-exclusive compilation album Thank You for the Music (1983), and become a minor top-forty hit on the UK singles chart.

"Thank You for the Music" also formed part of ABBA: The Movie which featured studio recordings of selected songs from the then newly released album ABBA: The Album. The song is included in the final scenes as the hapless journalist finally gets to broadcast his ABBA radio special, including an interview, on Australian radio. The song is accompanied by footage of a studio recording session, a live stage performance and a mimed studio performance by the four members of the group. The song also plays over the closing titles as the camera pans out from the band performing in a hut on an island in the Stockholm archipelago to views of the archipelago itself.
