The songs you hear on this cassette were sung and recorded in an old cold, empty, echoey flat on Leopold Place in Edinburgh. Away from home, stuck in the dark middle of winter.
It was the coldest winter there for more than 50 years. There was sometimes a blue hue to daylight on the very coldest of days, when the temperature fell to minus 14C. It was colder at night, colder still at home. Snow fell, trains stopped.
