A DIY label, from the Cleethorpes area. Bloodshot's single 'Softly Stroll' b/w 'Don't Step In My Path' seems to have been Rock Ma's (or RockMa's; different sources give different versions) only release. It came out in 1978, and had a catalogue number of GPJ-001. It seems like a good bet that the GPJ part were the initials of guitarist Graham Jarvis; perhaps he was responsible for financing the record. Thanks to Nicholas Hough for bringing the label to my attention and providing the scan.
