Secret Affair are a mod revival band, formed in 1978 and disbanded in 1982. They reformed to perform and record in the 2000s.

Formed after the demise of the CBS Records signed power pop band New Hearts, singer Ian Page and guitarist David Cairns spent the second half of 1978 writing songs that would form the basis of the first two Secret Affair albums. After spending January 1979 demoing songs, Page and Cairns enlisted the services of bassist Dennis Smith from the power pop band Advertising and Young Bucks drummer Seb Shelton. Saxophone player Dave Winthrop, originally playing with the group in his capacity as a session musician, would join as a full-time member of the band later in the year. The music videos for several of the band's songs were directed by Steve Barron. After the demise of the group in 1982, Cairns went on to form a band called Flag, with Archie Brown from The Bureau and signed a recording contract in the US he subsequently teamed up with Scottish singer Alan King in Walk on Fire, writing the majority of the band's material and playing keyboards on tours. Signing to MCA in the U.S., the band released the album Blind Faith in 1990 and toured supporting Foreigner, Nils Lofgren and Dan Reed Network before Cairns joined Gibson Guitars USA as Special Projects manager. Page released two solo singles before leaving the music industry. Having departed the band late 1980, drummer Seb Shelton most notably joined up with Kevin Rowland's Dexys Midnight Runners and enjoyed huge success with them between 1980 and 1982. In June 2002, Page, Cairns, Smith, Bultitude and Winthrop reformed for three gigs, including a performance at London's Shepherds Bush Empire. They returned in June the following year, playing at The Scala in Islington to promote the release of Time For Action: The Anthology (Sanctuary), a major CD retrospective of hits, rarities and previously unreleased tracks. The concert was filmed and released on DVD. Page and Cairns reformed Secret Affair as a touring band with a new line-up. In 2009 they have played regularly around the UK and further afield, having played their first ever concerts in Dublin, Madrid, Moscow and Tokyo. In July 2011, Secret Affair re-recorded "Time For Action" for Save The Children. The latter spearheaded their campaign for health workers in poor countries, and over 42,000 people signed the petition in the UK which was taken to David Cameron in September 2011, resulting in funds for the cause endorsed and approved by the United Nations. On 5 December 2011, Dave Cairns appeared as a guest on BBC Two programme, Never Mind The Buzzcocks. Secret Affair released their fourth studio album, Soho Dreams after an absence of 30 years on their label, I-SPY Records, on 10 September 2012, distributed by Code7/Plastic Head and supported by a 13-date UK tour ending at The 229 Club, London, on 24 November.
