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 in Christmas 1980 when they knocked former Beatle John Lennon's Happy Christmas (War is Over) off the number one spot with their sickly sweet tune, There's No One Quite Like Grandma.
They spent a week at number one before being replaced by another Lennon tune, Imagine.
The choir, now 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.
