Being a progressive bluegrass act they could rub some people the wrong way. I had to reprimand John Duffey once for being too vulgar on stage. (It was the Bishop’s Bluegrass Festival for goodness sake!)
They had a well-developed sense of fun, instrumental and vocal prowess, and high-quality output during an important time in bluegrass. "Live at the Cellar Door" was a landmark live album as well. All of this makes them an all-time great band.
