Definitely not. I'm in Winnipeg (Canada). My last quartet was the reason I left barbershopping. The other three members were more interested in the social aspect of being in a quartet. For them, learning the words and music and performing it well was secondary to having the right clothes, socializing, etc. I was in it for the music.
I would have stayed in the chorus but it was solidly stuck back in the 1920s. There was no attempt to modernize the music selection. As a result the chorus could not recruit younger members.
This is a portion of the poster for the 2014 show. You can see the chorus is definitely showing its age. I've seen videos of some American chapters and they are absolutely first rate. They have a good mix of all ages and they are serious about the music.
