 Described by band member Liz McClarnon as a "sort of a slow ballad but still quite funky," "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.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".
