Does this drummer drum like he's 73 years old?

That’s valid.

A few years ago I would have said no, he doesn’t drum like he is 73. But a couple years ago I saw Starship and The Babys in concert. Both of them had original drummers (I think!). The Starship drummer was going great and he was in his 80’s. You’d never know. So it made me question what my preconceived ideas of an old drummer would be. Of course when they took a break he had to be helped up off his stool and he could barely walk, but it didn’t affect his drumming!

And he will till the day he passes. Musicians who start at a young age have a different brain than ours.

Neil Peart was drumming up till he passed at 67. Hands down one of the worlds best drummers till the day he passed.
