The word itself, "Cabaret", carries overtones that conjure exotic pictures of nude dancers, the "Moulin Rouge" and German Beer Cellars; a sort of high-class iniquitous entertainment enjoyed by the lucky few. But that is all changed. It's been brought down to the level of the man-in-the-street. Now he can have a ringside seat for dining, dancing, drinking, a show ... and gambling.
Yet he won't take advantage of all this 'loose-living' unless there is also a "SHOW", as the proprietors of these establishments well know. There is a plethora of singers and 'groups', and insufficient speciality acts; which means a great deal of work for magicians ... if they can survive under the conditions.
In fact, it's very, very hard work. If you go into it, go in seriously, or leave it well alone. It is the field with the greatest commercial possibilities and the pickings are rich. They're there for you to take!
