Kim Wilde must have had a very good evening if she thought that she was singing on the Underground as this was patently an FCC Class 365 speeding its weary load home to Hertfordshire.
The first giveaway was the guy in the distance sitting in the luggage stack opposite the toilet door and then, of course, towards the end with the relief that the torture was over when the train is seen arriving at FCC's Potters Bar station.
