I don't know if Berry was still performing, but he was until recently. When I saw him, a couple times he got lost in a loop somewhere. He went back to the start of the song each time, sang it fresh. It was almost 20 years ago, on a "see them while you can" bill with Little Richard and Jerry Lee Lewis. Berry's the first to go.
There was no one better. RIP
Actually, it was announced last year that he would release a new album this year. No idea if that will happen now or not
