That song always makes me feel very sad. Fifty plus years ago as an eighteen-year-old I used to travel on the overnight coach from London to Manchester, which arrived in Manchester around 5am, giving me time to catch the first bus from there to my home town. As 6am approached there was a string of homeless waiting to get into the bus-station toilets for a wash and brush-up - "carrying their home in two carrier bags". No drugs in those days, other than alcohol, but the sight remains with me as a septuagenarian.
