The Barber Shop Quartet was amazing in talent! The overall performance was outstanding. I would recommend however, someone looking for a Quartet, to be more specific in the types of music they would like performed at their event. Several of the songs performed were a bit slow and a bit depressing for a birthday party event. This is most likely due to my inexperience with Quartet performances. There were several requests for business cards from the group for future performances. Many compliments from the guests. Overall I would recommend David Patterson and his group to any one. Highly entertaining!
