It's hard for me to personally think of people that are still writing new material and touring new material as oldies....
that usually comes under the heading of one or two hits and now they're touring on the strength of those one or two hits...
Even harder I suppose when the people are chronologically in the oldies department, but still ridiculously vital when it comes to performing.
(Now I'd be talking about bands like the Allman Brothers and the remaining members of the Grateful Dead, and the Rolling Stones, and yes, I'm that old too...)
