Children in Need is the BBC's annual telethon to raise money for disadvantaged children around the UK. They usual release some sort of charity single, and this year the comedian Peter Kay arranged for cartoon characters / children's TV characters to sing a medley of songs. Don't Stop is one of them. Utterly bizarre, but all for a good cause.
