Junior, I remember seeing a jacket draped over a bar stool near the tables where the books were when myself, Trev & Tarby left at the end.
There were still about 10-15 people left in the room including yourself, so I assumed the jacket belonged to one of them. This was presumably yours.
The best bet is for Trev to phone the bloke behind the bar, then I will walk round and get it (tomorrow ?) if it's still there.
Trev's probably in Court at the moment and won't see this message until this evening though.
