Horrible place on the Essex coast and only about an hour up the A12, but people would take their caravans and stay for a fortnight. One of my many uncles had a caravan up there and when I was very young, we went to stay in it. One morning, a small caravan two along from ours seemed to be rocking up and down of its own accord. It wasn’t even windy but this caravan was jigging about so enthusiastically that I was convinced it was going to break loose and roll into the sea. I asked my dad why it was rocking like that but he said nothing and just led me away. It was only when this record came out many years later that I suddenly remembered that caravan and what its occupants must have been doing.
