Rancid (UK)/Before After demos 1986

This Rancid is the UK band and not the well known American band. I'm not sure if Before After is the name of their record or the name of another band. I think this is two bands but I could not find any information on the internet about them. Can anyone help? I think these are demos. Sound quality is very good.
