The good news is that the majority of the Facebook comments were quite positive.  I do agree with owllover that a song like Apologies is a good gateway into GPN's music.  Friends I introduce to the band via that song are much more receptive to hearing more after they start with a song that has that kind of general appeal.  Things I Never Needed might have been a good single to start with ... but then they'd have been pigeonholed as alt country which I'm guessing is not where they want to be (for good reasons, given the diversity of their musical style).  One thing's for sure, you can't please everyone ... fortunately, most FB commenters really liked the performance.  Personally, I thought they nailed it. :)
