on the writing of the song:

Sheriff J.H. Blair and his men came to our house in search of Sam – that's my husband – he was one of the union leaders. I was home alone with our seven children. They ransacked the whole house and then kept watch outside, waiting to shoot Sam down when he came back. But he didn't come home that night. Afterward I tore a sheet from a calendar on the wall and wrote the words to 'Which Side Are You On?' to an old Baptist hymn, 'Lay the Lily Low'. My songs always goes to the underdog – to the worker. I'm one of them and I feel like I've got to be with them. There's no such thing as neutral. You have to be on one side or the other. Some people say, 'I don't take sides – I'm neutral.' There's no such thing. In your mind you're on one side or the other. In Harlan County there wasn't no neutral. If you wasn't a gun thug, you was a union man. You had to be.
