Staff and patients at Alder Hey Children's Hospital in Liverpool have released a charity music single.
Their cover of the S Club 7 hit "Reach for the Stars" features 13 year old Grace Lee from the Isle of Man, who's been treated at the hospital since she was just 8 days old.
It's a way of giving back and just saying thank you for all that they've done.
Hers is just one of the many inspiring stories to be featured in the song.
