has there been more than one version of the play macbeth? If so which ones are performedmost often? Why?

Answer 1

There's only one "Macbeth," by William Shakespeare. However, having said that...modern editors of the text always work from a particular source (every edition will have an introductory chapter called "A Note on the Text," or some such), and, with certain of Shakespeare's plays, there is considerable disagreement as to WHICH of the extent printings is the proper starting point for a modern edition.
