A night of fun after a day of Christmas shopping. We were lucky to be with other passengers who entered into the 'spirit 'of things which added to our enjoyment. This would be ideal for a group outing. The lady bus conductress set the mood so well and her enthusiasm was infectious. She held our attention with historical facts interspersed with quirky fun stories. I would have been happy with her dialogue alone throughout . Who would have thought the curve in the Piccadilly tube line was due to ........ no I can't tell . You will just have to ride the bus for yourself. Have fun.
