The Arboretum club, Nottingham, early 1980s.
Announced as a “last dance” the final record of the evening tended to be a slow romantic ballad to encourage the coupling of new or existing partners.
For people in groups or uncoupled this was the opportunity to drink up and start putting on their coats but for some it was time to rebel and make a statement.
(Interesting to look at nightlife pictures taken (by others) more recently, seems there has been a shift in behavior since the 1970s / 1980s, a more “mass experience” crowd based aesthetic)
