Well, yes, I have some years behind me but they are still touring; see Blue Öyster Cult Tour Dates, although I don't know how many of the original members are still with them.I think you have to be pretty old to remember who that was. They did a concert in San Diego when I was in college, admission was a donated can of food.
I saw them several times back in the 1970s and 1980s; they were phenomenal in those days. I even got to see their laser show that some gov't agency shut down to make them stop shining the lasers into the crowd. Killjoys.

More cowbell!
