(WWW) A website by Isaac Wexler has included a history of busking as a means to promote his courses on successful street-performing. A busker for over ten years, Busker Pro is his way of giving back the knowledge and experience of his career as a busker.
Some interesting notations include the furthest recorded history of law affecting buskers in ancient Rome back in 462 BC. It was made a criminal offense to sing or make parodies about the government or officials in public places. The result was a very harsh death penalty to the performers without noble protection from the privilege of justice.
Another was in 1530 when Henry VIII ordered the practise of minstrels and players, fortune-tellers, pardoners and fencers, as well as beggars that if they did not obey the law, they could be whipped for two days.
There's also a free 10 page ebook available on the site - My Life As A Busker.
