"The Last Goodbye" was written by Norwegian musicians Hallgeir Rustan, Mikkel Storleer Eriksen and Tor Erik Hermansen, a trio of Norwegian musicians who work under the production moniker Stargate, along with frequent collaborators Espen Lind and Peter Björklund and British DJ Daniel "D Mob" Poku:^[2] It is one out of two tracks Stargate contributed to parent album Feels So Good (2002), the other being lead single "It's OK!".^[2] Recording took place at the Metropolis Studios in London, while mixig was helmed at the StarGate Studios in Norway.^[2] Bernt Rune Stray played the guitar.^[2]

Described by band member Liz McClarnon as a "sort of a slow ballad but still quite funky,"^[3] "The Last Goodbye" was re-recorded for its single release to include solo parts of each Atomic Kitten member. While the original version features Natasha Hamilton on lead vocals on both the first and second verses, portions of her vocals were replaced on the single version, with McClarnon and Hamilton splitting the first verse and Jenny Frost and Hamilton sharing the second verse.^[2]

In Ireland and the United Kingdom, Virgin Records released "The Last Goodbye" on a double A-single along with the previously unreleased song "Be with You".^[4] Both songs served as the album's third and fourth single, respectively.^[4] In the United Kingdom, it became the band's eighth top ten hit, peaking at number two on the UK Singles Chart in its first week of release.

For the music video for "The Last Goodbye" Atomic Kitten re-teamed with British director Jake Nava with whom they had previously worked on the visuals for "It's OK!" and "The Tide Is High (Get the Feeling)". The majority of the video filmed on 16 October 2002 and set in night-time Liverpool.^[3] According to band member Natasha Hamilton, the reason the video was filmed in Liverpool, was "because [they] wanted a location with beautiful architecture, and tourist attractions that people will instantly associate with Liverpool."^[3]

In the music video, the band members portray three women in differing scenes, who stumble upon various lovestruck couples, whilst they themselves are alone.^[3] Liz McClarnon said that it was their first video where they had to include acting, instead of dancing, posing and just singing in front of the camera.^[3] Some of the scenes include McClarnon at the Plaza Community Cinema and Jenny Frost in a hotel room, looking out on the balcony. Scenes of Hamilton at the Liverpool Airport were filmed in front of a greenscreen.^[3] The final scene includes all three characters walking down a famous sight in Liverpool, again, in the dead of night.
