There is no limit to a a musician's creativity..
Accept that Heavy Metal and Electronica shanties exist
and are enjoyed by younger audiences,
who probably know eff all about folk clubs and folk law enforcement agencies...

Folk Police...???

Howabout...

Folk Special Constables..??

Folk Community Support Officers..???

Folk Traffic Wardens..????

If those are to formal and you don't fancy wearing the uniforms..

What about Folk Neighbourhood Watch..???

The Folk Militia...???


I quite fancy the option of Folk Vigelantes..
going dark and rogue like Batman..

... the Folk Caped Crusaders...
