Classical guitarist John Williams reached millions of ears and even hit the charts when he played the main theme to the Oscar-winning 1978 film The Deer Hunter. But by then, Williams was already a classical star on a major record label who'd toured the world many times over.
He released his latest album, On The Wing, earlier this year. And although he announced a retirement from touring a few years ago, he's now 76 and still plays every day.
"But I love doing it so it's not a problem," he says.
