В TEDxРотердам, световният шампион по свирене с уста Герт Шатру изпълнява насмешливата "Елеонора" от А. Хонхоф и собствената си "Фет де ла Бел" (Празника на Хубавицата).  В завладяващ антракт, той говори за това, което го е довело до този занаят.

Свирач, какъвто не сте чували

Whistling, once dismissed as an irritating quirk, became the gateway to unexpected achievement and joy. After years of playful persistence and a nudge from a family joke, a Dutch whistler found himself competing in, and winning, world championships. What began as a habit at age four transformed into an international career, even prompting him to leave his job as a nurse. Through humor and audience participation, he shows how an odd passion can unite a crowd and open unforeseen doors.
