Lauder was described by Sir Winston Churchill as Scotland's greatest ever ambassador, who ... by his inspiring songs and valiant life, rendered measureless service to the Scottish race and to the British Empire. He became a familiar worldwide figure promoting images like the kilt and the cromach (walking stick) to huge acclaim, especially in America. He first toured America in 1907. The following year, he performed a private show before Edward VII at Sandringham, and in 1911, he again toured the United States where he commanded $1,000 a night. He was, at one time, the highest-paid performer in the world.
