See the movie. Im a huge fan of the movie and then going there and seeing how perfectly they recreated Big Edie and Little Edie was amazing. Plus, youll get the little inside jokes that are peppered within the show, which makes it much funnier. ALso, I would refrain from listening to the recording, just because I love the suprise of going into a show not knowing whats coming, but thats just me.
