Caught the Who at the Santa Barbara Bowl a few years ago. They are in their 70's. Still great. Townsend doesn't leap around anymore but he did one hop at the end just to show he's still got it. Starkey is a credible replacement for Moon.
Santana still going strong. As long as he hydrates.
Van the Man. Ian Anderson. Lonnie Jordan. The Geezers keep rolling on and an inspiration to us all.
