Although Mills' musical legacy had been largely forgotten in recent times, June 2012 saw the emergence of London-based tribute band The Mrs Mills Experience with a debut at The Vintage Festival at Boughton House in Northamptonshire. On 13 July, they were filmed playing live at The Prince Albert pub in Brixton, London Borough of Lambeth by the BBC. On 23 September 2012, BBC Four broadcast the 60-minute documentary "Let's Have a Party! The Piano Genius of Mrs Mills" on the life of Mills, which included footage of the band and contributions from Rick Wakeman, Rowland Rivron and Pete Murray, amongst others.
