Hoot, okay, there is stuff on this in Abbot and Seroff but it is vaudeville rather than tent shows. Again from memory they had 'shills' in the audience demanding a particular tune which they then planned to sell outside. But at the moment I'm just googling and looking at extracts. This really should be on another thread. Sorry, to all. But bringing it back to the discussion might the idea solve the problem about where Pardon's grandfather got the tunes if he got the words from broadsheets?
