The massed ranks of St Winifred's School Choir are getting back together on TV for the first time in decades to see if there is still no one quite like grandma.
The angelic young singers from Stockport rose to fame - and the top of the charts - in Christmas 1980 when they knocked former Beatle John Lennon off number one spot with their sickly sweet tune.
There's No-One Quite Like Grandma spent a week at number one having knocked Lennon's song Happy Christmas (War is Over) off top spot, before being replaced by another Lennon tune Imagine in the wake of the murder of the ex-Beatle.
The choir, now aged in their 40s, will appear on a Channel 4 show with a working title Rewind It's Christmas.
Among the original members was Sally Lindsay who starred in Coronation Street as barmaid Shelley Unwin before helping create hit cop show Scott and Bailey.
Fourteen members of the choir reunited five years ago to record a new version of the song for charity.
The show also includes a performance by glam-rockers Slade and The Darkness and an interview with The Pogues frontman Shane MacGowan and the family of Kirsty MacColl about the inspiration behind The Fairytale Of New York.
