You don’t often see really old rockers.
Shhh, you'll make Kieth Richards nervous!
I doubt too many are going to make it to 80. I was surprised Kantner even made it to 74 -- although, technically, he was not a Baby Boomer. The oldest BB, in fact, would be 70. I see a lot of BBs dying in their 60s -- including my older brother, who dropped dead at work at the age of 61.
Chuck Berry, Little Richard, Jerry Lee Lewis, Scotty Moore, and Fats Domino are all still around.
