It was his mother’s birthday, and he was in Rotterdam. They were playing the Beethoven violin concerto, a family favourite.
Roger Federer was not going to miss it. Nor were the players going to miss him. Here he is, coming backstage with Rotterdam Philharmonic managing director Hans Waege (left)
And here he is mingling with the players while his Mum (right) strides ahead.
Thanks to Leonike at the Rotterdam Phil for the snaps.
UPDATE: This, I hear, is no one-off. Here’s Roger tipping his hat to the Sydney Symphony Orchestra.
