Can you name a successful rock band member who was aged 30 or older when the bands debut album was released?

Charlie Watts of the Stones. Alexis Korner of CCS. I actually saw Korner (drunk) in Regensberg accompanied by his son and daughter (both drunk). A lot of musicians who were in Steam Packet in the early days ?had hits after years on the road. Jerry Jeff Walker? Ginger Baker? Andy Newman?
