Book excerpt: Drama, opera, ballet, circuses, concerts, and puppet-shows: down the years, all these species of live entertainment faced innumerable difficulties in Ireland. The challenges that are the focus in this unusual study are those that touched on matters of law. Assorted venues encountered episodes of censorship and of riot. Safety of buildings, performers' contracts, dramatic authors' performing rights, liquor licensing all merit attention too, as, indeed, necessarily must the issue of the lawfulness of any 'theatrical' activity itself, given the ill-defined powers of the Irish Master of the Revels (1638-1830) and the controls exerciseable under the Dublin Stage Regulation Act (1786-1997).
