A bit of an aside prompted by your comment about "lab coat", yankmod. White labcoats, or what we knew as "butcher coats"*, (but quite distinct from macs) were fairly common gear on football terraces in the Later Bootboy Period (this is starting to sound like geology ). Round about the time of wider, baggier denims worn with DMs: from memory about 1975 - 1978. The white colour allowed the wearer to customise the coat with their own "artwork": team and player names, club crests, slogans, general threats of impending violence, abuse of rivals etc. usually worked up in coloured felt pen. They could vary between fairly impressive artwork almost like tattoo art at one end of the spectrum and pretty scruffy scribbles at the other.
* think of a white version of the warehouseman's coat that Ronnie Barker wears as Arkwright in "Open All Hours". (Glad to hear you've got into that, it's absolutely classic.)
Thanks for the info elwood.Remember seeing a few blokes in old Football footage and wondered what they was up to(thought they was butchers just off work)Watched "Going Straight" Now watching "Clarence" "Two Ronnies" will be next.
