One of my favorite a cappella groups is the Canadian band the Nylons. They’ve gone through a number of members of the years, and only one of the four founding members is still alive (one died of AIDS in 1991, sadly, while still active with the band; the other three retired from the band and died more recently), but they’ve remained a great group throughout their run from 1978 until their farewell tour in 2016. Here’s their stupendous cover of “Duke of Earl.”
