On New Year's Day 2011 Wood appeared in a BBC drama Eric and Ernie as Eric Morecambe's mother, Sadie Bartholomew.  For the 2011 Manchester International Festival, Wood wrote and directed That Day We Sang, a musical set in 1969 with flashbacks to 1929. It tells the story of a middle-aged couple who find love after meeting on a TV programme about a choir they both sang in 40 years previously. Although the characters are imaginary, the choir sang with the Halle Orchestra in Manchester's Free Trade Hall on a record that sold more than a million copies. Apart from the pieces on the 1929 recording (Purcell's "Nymphs and Shepherds" and the Evening Benediction from Hansel and Gretel) the score for the musical was written by Wood.  On 22 December 2012 Wood was a guest on BBC Radio Two's Saturday morning Graham Norton Show. On 23 December BBC One screened Loving Miss Hatto, a drama written by Wood about the life of concert pianist Joyce Hatto, the centre of a scandal over the authenticity of her recordings and her role in the hoax. In April 2013, Wood produced a documentary about the history of tea named Victoria Wood's Nice Cup of Tea. In 2013 she played retired constable-turned-security-guard Tracy in BBC Scotland's Case Histories starring Jason Isaacs. She appeared in an episode of QI, broadcast on 13 December 2013, and around the same time made two return appearances on I'm Sorry I Haven't a Clue during the show's 60th series. In March 2014, Wood voiced the TV advertisement for the tour of the old set of Coronation Street. On 5 December 2014 Wood was a guest on BBC's The Graham Norton Show. On 26 December 2014, a television adaptation of That Day We Sang, starring Michael Ball and Imelda Staunton, was shown on BBC Two.  In early 2015, Wood took part in a celebrity version of The Great British Bake Off for Comic Relief and was crowned Star Baker in her episode. She co-starred with Timothy Spall in Sky television's three-part television adaptation of Fungus the Bogeyman, which was first shown on 27, 28 & 29 December 2015, her last acting project and final role.
