That's how an orchestra celebrates their "birthday children" during a tour.
A special birthday "brass" serenade was played at Seoul Airport for Florian Abächerli, Maria Kagan, Raphael Christ and Raymond Curfs who celebrated their birthday on the Lucerne Festival Orchestra tour through Asia.
On the flight to Beijing and after the Birthday serenade, Thomas Roisland's tuba needed an extra comfy seat with lots of legroom.
