Twentyfourseven was released as a free insert in The Mail on Sunday's 4 May 2008 issue, which sold nearly three million copies. This however, led to a backlash when the full 17-track version was released 21 June 2008, and most of the big retailers refused to stock it. It reached #81 in the UK Albums Chart in the UK. This was a first for UB40, as all the official albums had previously gone Top 50 on the UK Albums Chart.

The track "Rainbow Nation" refers to Gary Tyler once again, originally the subject of "Tyler", the first song on their first album, Signing Off. The original saxophone part from "Tyler" is played over the closing bars of the track.

UB40's next release (on EMI) was a collection called Love Songs. This reached number 3 in the UK Charts.
