Though I've visited NYC several times a year for decades, I now live here so I have no reason to venture into the usual suspects like One Shubert Alley and Theatre Circle.
Many years ago I used to pop into Theatre Circle and scope out their vast and extensive selection of old souvenir programs: Broadway, national tours, Vegas, West End -- they had EVERYTHING, not just the current shows. I popped in last week into Theatre Circle and sadly, they no longer carry anything like that. Their inventory now is solely a few of the current shows and that's it. In fact, the store itself looks quite smaller than it did years ago. Oh, well. Those visits to the store many years ago was such a fulfilling hour visit. Last week I was out of there in 3 minutes.
