I’se the By That Catches the Fish…and Other Things, Yo!

LIstening to CBC radio this morning on the way in to work, and there was mention of some concert or other taking place at Hugh’s Room in Toronto.  Spouse told me that she had been to Hugh’s Room once, several years ago, to see some “singing fishermen group”

My quizzical look was a silent entreaty for more information.  She told me they were “West Coast clappy” guys.

I am unfamiliar with this particular genre of music (part of my brain is wondering whether the said performance involved Captain Highliner, Tupac Shakur and chlamydia).  Can anyone enlighten me?
