london , 1797 `` we 'll be back for the rest of the lot in a few days , '' allows one of the men , and he 's right 'cause me mum and me sister both goes off the next day and the men come back and takes me mum and puts her in the cart , her legs all danglin ' over the side and not covered up proper , but it 's muck that comes and picks up me poor little sister and throws her all limp over his shoulder .
