Not many people know this, but Paul Robeson once went through a profound hypochondriac stage. He stayed in his hotel room with cold compresses on his head drinking Lemsip all day. His manservant felt very left out. Then one day he got in the lift only to find himself standing opposite American Nazi Party founder George Rockwell. He lunged at him, planting his teeth in the loathsome racist's wrist, then got out at the next floor and ran to join his boss in bed for a Lemsip. 'What's all this then?' inquired Robeson. 'I'm just like you', explained his manservant, 'a valet chewed an Aryan.'
