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.^{[citation needed]} Choirmaster Andrew Stewart took over, and rehearsals began in September 2006.

On 19 December 2006, twenty members of the choir performed Handel's Hallelujah chorus in private performance at Buckingham Palace for Queen Elizabeth II, the Duke of Edinburgh, and others; they also sang carols for guests at the 'Achievers of the Year' reception.^{[citation needed]}

On 14 January 2007, 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.^{[citation needed]}

On 14 February 2007, the choir performed with Oxford Philomusica at 'A Night at the Movies' at the local BMW factory, and on 24 February 2007 at Oxford's Sheldonian Theatre with the Oxford Philomusica and two guest solo singers.^{[citation needed]} In 2008, they performed again at the Sheldonian Theatre, with Julian Lloyd Webber and the Oxford Philomusica.

In 2009, the choir performed a number of public concerts, and in August visited Oxford's twin town, Leiden, for a series of small concerts as part of the Rapenburg music festival.^{[citation needed]} In 2016, a tenth-anniversary concert was held.^[1]
