While checking out the pubs of North Shields last night with Chris, YC noticed this picture on the wall of The Low Lights Tavern. The chap with his arm round the barmaid's shoulder is John Duff (click on the photo for more detail).
And here is the caption under the picture which proves it.
But just in case any readers think that YC's satorial style is even more out of date than it actually is, YC can reassure them this picture was taken in the 1950's. The John Duff in question is Timothy Duff's cousin, so that makes him YC's first cousin once removed.
