THE GREAT AMERICAN TRAILER PARK MUSICAL
SEUSSICAL
I mean...there is a difference between talking to the audience and giving and "aside" remark to the audience. Plays with narrators, such as To Kill A Mockingbird, obviously break the fourth wall. But then there are shows where characters reference remarks (an aside) to the audience.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
