BM Productions Records was a DIY label. An EP by Billy Mac, 'Cornish Grumbles' A tale of one of Cornwall's oldest beers, dates back to the time when they used to load treacle from Joppa mine on to Packet ships in Barripper harbour. Appears to have been BM Productions' only release. It featured 'How's It Feel' and three other tracks, and had a catalogue number of BM-001. A release date of late 1976.
