lol, yes I know about it – I went last year because a friend invited me.
I would use the term “rock” bands very lightly considering the main stage was some band called Nickel Creek (I think). They are a very light band more of a folksy/bluesy/light sounding band.
It’s all clean music. They have other things as well including cotton candy, popcorn, tons of other food and yes, beer.
Overall I think it is a very good even and still repectful of the church and its grounds.
