This morning Jodie & Soda spoke to Tiana from Banksia Park, who tweeted superstar Katy Perry about her sister Grace, who is undergoing cancer treatment and was too sick to come to her shows.

Katy’s management found out about it, and organised a visit for Gracie and her family and even sang a few songs!

Well done Tiana, we’re super proud of what a great sister you are.
