Every good story requires Original Characters, and Sir Matthew Bourne's The Midnight Bell is no exception. Albert is a chorus boy in the West End and gay, which was a bad idea in 1930s London. Patrick Hamilton did not write any gay characters (for obvious reasons), but it is not difficult to see Albert in that setting.
Albert walked quietly into the pub and noticed it was already fairly busy. He nodded to a few of the other customers who he recognised, bought himself a pint and settled down at a table which was at a distance from the majority of customers. That suited him well, he didn’t mind an exchange of greetings, but had no wish to engage in conversation. Fortunately, there were a few others who were also on their own, either waiting for their mates to arrive, or enjoying the peace before heading home to their cramped accommodation, their harassed wife, and several children.
