"Are there any more real cowboys?" Neil Young sang Saturday night at the Hollywood Bowl on a rare evening when he was neither the headliner nor, at age 77, even close to the oldest artist on the bill.
Providing an instant answer, Willie Nelson, wearing a cowboy hat and red-white-and-blue guitar strap, slowly strolled on to the stage on his 90th birthday, bringing the crowd of more than 17,000 to its feet.
Nelson sat in a chair — one of the few onstage concessions he's made to age — and joined Young for the rest of their 1985 duet, "Are There Any More Real Cowboys?"
"I want to thank all the artists who came out tonight to help celebrate whatever it is we're celebrating," said Nelson, feigning senility and getting a laugh.
