Björn can be seen very briefly during this video supporting two brain tumour charities: The Brain Tumour Charity and brainstrust.

To celebrate a year since seven year-old Ravi's brain surgery, after discovering a benign tumour, a stellar cast of internationally acclaimed musicians and celebrities gathered in Ravi’s name to record a charity music video raising money for children with brain tumours.

The video for Ravi & Friends’ cover version of A Million Dreams' from The Greatest Showman features Ravi, as well as Coldplay, Bastille, Damon Albarn, Paloma Faith, Mary Berry, Björn Ulvaeus, Heather Watson, and many, many more.
