PURCHASING my concession ticket at Cowcaddens subway station at the weekend for my first spin on the Clockwork Orange since its reopening, the lady serving me issued my brief with a lovely smile and a "thanks, son." At 61, I can tell you she made my day. You wouldn't get that on the London Tube, Paris Metro, or indeed the New York Subway, all of which I've been on. Long live the Glasgow Underground.
