I filmed Ola singing Ise Oluwa (e-shay o-loo-wah) outside the King's Palace in Abeokuta. It's was a beautiful moment.
The song is a Christian Yoruba song which roughly translated means that 'What god has made cannot be undone'.
Shyla Nelson, who I was filming with, plans to have people all around the world sing the song as a way of encouraging us to take care of the planet.
