The Allisons was an English pop duo consisting of: Bob Day (born Bernard Colin Day, on 2 February 1941, in Trowbridge, Wiltshire) John Alford (born Brian Henry John Alford, on 31 December 1939, in London) - not to be confused with 90s UK pop starJohn Alford. They were marketed as being brothers, using the same surname of Allison. The Allisons represented the United Kingdom in the Eurovision Song Contest 1961 with the song "Are You Sure". They came in second place with 24 points. The song was released as a single on the Fontana Records label, and climbed to number 1 on the UK New Musical Express pop chart.

However, the official UK singles chart shows the song reached number 2. Despite a couple of minor follow-up hits, the duo disbanded in 1963.

John initially tried song writing, and they teamed up for short tours to keep 'The Allisons' name alive. Additionally, in the 1970s and 1980s John was joined by other "brothers" - Mike "Allison" and Tony "Allison".
