This is going to drive me demented now. JR here with the grey hair (AI pic) reminds me of a slimmer version of an actor if you squint a bit and I just can't remember his name. He's Northern, poss Yorkshire, often plays coppers or wrong 'uns, mostly seen him in police/crime type things, generally not comedies, probably in his 70s now. Who the f is he?! Aaagh!
