Sam (JK) Simmons of www.somersfolklife.com (et al) fame is Welsh and Jewish.
He always smiles when people ask him to sing one of his favourite songs Kosher bailey.
He always entreats others to add verses too.

my new verse
Cosher Bailey's MP "Ron", well he stop awhile in Clapham.
Lost his car & job, but he still don't know what happen
who said political invective had dissapeared in Folk Clubs?
