The Singer factory in Clydebank west of Glasgow (such an enormous factory it had its own railway station, still there) was used for arms manufacture during WW2. Which made it a primary target for the German bombers in the Clydebank Blitz. Hundreds of people died and whole streets of the workers' housing were obliterated. But as far as I know there are no songs about it.   Official secrecy meant it wasn't made public knowledge for years.
