Forty years ago, Sunderland band Toy Dolls took a quirky children's song, Nellie the Elephant, and transformed it into a punk rock anthem that quickly became a fan favourite.
But the track's story is about more than just a catchy tune - it is about a battle for the UK's number one spot in the pop charts in Christmas 1984.
Originally written in the 1950s, Nellie the Elephant had long been a well-loved children's song.
When Toy Dolls dropped their punk-infused cover, the track became a sensation, selling more than 530,000 copies.
