The only founders of rock and roll still alive (as far as I can recall) are Little Richard and Fats Domino. Richard is 84 and Fats is 89.
If Domino makes it past this year, he will replace Berry for 2018. Thing is, I believe Fats has had history of bad health for some years now. It's still weird to see these three outlive a lot of the legends that would be inspired from them.
