For more than 40 years, AC/DC have been one of the coolest rock groups on the planet - almost as cool as the Glasgow winter that gave Angus and Malcolm Young Australian passports.
Intense blizzards swept across Scotland in the early months of 1963, with temperatures dipping to as low as -22 in some regions. It was the worst winter on record.
