"Food for Thought" was the first single released by British reggae band UB40. It was released as a double A side along with "King", which was a song written about the late Martin Luther King, questioning the lost direction of the deceased leader's followers and the state of mourning of a nation after his death. It was the first single to reach the UK Top 10 without the backing of a major record company.
It reached No. 4 in the UK Singles Chart in early 1980 and No. 1 in New Zealand in September 1980.
The song is regularly played at Birmingham City FC home matches, while the main tune is sung by the supporters during matches.
The original single version is slightly shorter compared to the "Signing Off" album version, with the album version including a break using a synthesiser reverb (an early example of their mixing techniques that can be found on their third album "Present Arms in Dub").
