Percy Fawcett the English explorer who was lost in South America was once saved by the accordion.
On one of his earlier trips, he was going down a river in a dugout canoe and passed an unfriendly native village - they started firing arrows, some of which went through the sides of the canoe. He pulled out his accordion and started playing a tune and they stopped shooting, eventually inviting him over. He stayed with them for a while and even hired some of them as guides.
