The Blackbird Leys Choir formed in January 2006 as 'Ivor's Choir' for a constructed documentary series, The Singing Estate under Ivor Setterfield. Original members all live or work on or around the Blackbird Leys estate in Oxford, England, and the series focused on their quest to become a classical choir in just three months.
After performances in Oxford, Italy, and at the Royal Albert Hall in London, the choir's future was uncertain for a while, but core members remained keen after filming ended, and in summer 2006 it was confirmed that there was funding for performances in February 2007. Choir master Andrew Stewart took over, and rehearsals began in September 2006.
On 14 January2007 the choir reunited with Ivor Setterfield for Oxford Sings, with other singers from around the city and county, to sing the Hallelujah chorus in a one-day workshop. This performance was recorded for broadcast on BBC local radio, and filmed for inclusion in a 'one year on' documentary by the makers of The Singing Estate.
