Ahh.... The Trip to Jerusalem! That was where my husband's stag night crawl "mislaid" the best man in 1976 when he went to the loo (and they moved on). He never located them again that night. It was the first pub I took my son to at 8 days old (had to sit outside 'cos of licencing laws). Unfortunately I think public health has cleaned the pub up from what it was all those years ago. They removed the cobwebs several times in the past from the model ship that hung over the upstairs bar, and I bet they've done something to combat the sand that dropped into your beer from the cave roof of the upstairs bar. God bless beermats.
Re the Four Alls sign: I think there is a king's head on there. The Hanging Gate rhyme also used to be on a gate-style sign at a pub on the Ashbourne road out of Belper.
