Okay, we've all done it.  We've violated performance/copyrights by cutting a foul word here and there, changing a date or two, etc.

But here are some questions:  who is the publishing house?  Samuel French and Dramatists Play Services are very picky about absolutely no cuts, no changes, etc.  Whereas, Pioneer Drama Service allows foul language changes, the saloon being changed to a hotel, the beer becoming rootbeer, etc.  The publishers that cater to high schools and community theaters also understand when you just can't present a song or two because your performers are not suitably talented.

Know your publishing house and realize you are paying for the privilege to present the playwright's work they way he wanted it presented.  By the way, when a play's timeline says "The Present Day" they generally are referring to the date the play was first published, not the date you perform it.
