Saw this August 24th. I enjoyed it, but.... I am not sure that the guitar and the rather odd songs (both the music and the lyrics) really added anything to it, and possibly even detracted from the performance as the actress had to take time picking up the guitar, putting it on, putting it down, etc - over the 10 or so songs, this added 10 or so silent (and useless) minutes to the length of the show. Had this benefitted the show, it would have been worth the interruptions in the storyline, but as it didn't, in my opinion, it wasn't.
Can't fault her for the mike cutting out now and then, but this too took away from the overall effect.
The story was interesting and the a/v was excellent.
