Wow, what a story! I've often wondered about the many people who have claimed to be The Real Billy The Kid. But hey, the Emperor Nero had been dead a while when a pretender hit town, claiming to be him, playing the same instrument, wearing a laurel crown, whatever; huge crowds gathered, fed him, put him up for the nights, hung out. Nero had been pretty popular with the general populace.
However, the pretender was rounded up by the gendermes and vanished into Roman prison, never to be seen again. :')
