Here's another very old flyer (click to enlarge). This one is for a Grand Masquerade, Garden Party and Fancy Dress Ball at North Woolwich Gardens (East London) on 22 July 1886. This event featured 'Dancing on the Monstre Platform from 4.00 pm to 2.30 am' and 'Dancing in Theatre' from 9 pm to 2.30 am with 'visitors in costume or fancy dress only' allowed to dance in the latter. The gardens were to be 'illiminated with thousands of lamps and Japanese lanterns'. All this for a shilling - that's 5p of your modern money, albeit worth a bit more in those days.
There was a special train back to Liverpool Street station at 2:45 am or a boat across the river at the same time for those heading back to South London. You didn't think staying up late dancing was invented in the 1960s did you?
