The venue was pretty run down but we were trying to make the best of it. A fellow traveller ran up to me. “Say, do you remember that film?”. I did not. Then she brought out a 1970s ‘movie viewer’ which I was able to wear like a pair of bulky spectacles.

Suddenly I could see Christopher Walken and two lovely women dancing glamourously down a staircase in 1930s evening gowns. It was the exact staircase we were standing near, but in its Hollywood heyday.

“Well aren’t you a clever thing?” I said. I just wanted everyone to be friends.
