This book traces the history of the Music-hall in Scotland in a clear and scholarly manner. If there is a theme running through it, I would think it would be "it's more complicated than you think". That is to say, the author tries to understand Scottish music hall and not just to recount it, and comes up with interesting hypotheses on two issues :
Firstly, he underlines the fact that the music hall performers in many Scottish halls were closely linked to their audiences, many were part-timers who lived with the people they played for etc.
Secondly, he claims that the use of stereotypes of Scotsmen on the music hall stage cannot only be understood as an English-inspired mockery. Scottish stereotypes were also used to project a unified image of Scotland in reality divided between towndwellers and highlanders, and these images were very popular among exiled Scots.
