A Whitfield hero story

Nick quotes Spurgeon telling a story about Whitfield:

George Whitefield said, when he preached on Kennington Common, where they threw dead cats and rotten eggs at him, "This is only the manure of Methodism, the best thing in the world to make it grow; throw away as fast as you please." And when a stone cut him on the forehead, he seemed to preach the better for a little blood-letting.

I reckon Al Stewart would like that quote.
