The barbershop style originated with guys hanging around barber shops, harmonizing to the popular songs of the day. One of my goals as an arranger is to maintain that focus and keep making sure the popular songs of our day are part of the art form. Songs don’t get much more popular than Ed Sheeran’s “Perfect,” which was a huge hit in 2017. I was asked to arrange it for the quartet Impact, who took it to the BHS International stage in 2019.
