The video above is part of British Pathe's archival footage of London.
Come To London, by British Pathe in 1966. This short clip shows a couple using a "water motorbike" on the Thames and Britt Ekland cutting a publicity stunt cake that Peter Sellers drivers out of in a Minnie!
You can watch the full 8 minute video here.
I really love these old movies about how London looked in the past. It's funny how some places, such as the Houses of Parliament, look exactly the same as today. Whereas other things, such a reporters working on fleet street, have virtually disapered. A nice reminder of how some things change and others remain the same in London, but that it's always hard to predict which will be which.
