Today I got a letter addressed sent to me at the theatre (addressed to the Stage Manager) with a very polite letter requesting a copy of our Playbill signed by the cast. This was the first time that I've gotten this kind of letter, though I know it is fairly common place for bigger productions, and I learned that it feels good to know that I'm going to be making some fan's day when they receive a playbill in the mail in the near future.
This letter, by the way, came from somewhere in Alberta, so it's also cool to know that my show has fans from that far away (though I'm guessing this person is primarily a fan of one of my cast, who happens to be a Tony winner from a certain musical that opened in 1996 and ran for quite a few years. We had a few audience members at our first preview last week who came from Tennessee and planned their NY trip specifically for our show and the chance to see him, so that was really cool seeing their reaction when he came out to meet them after the show).
