Independent Reggae label: King George Records. It managed at least one singles. 'Mixed Up Man' by British band Black Slate; it came out in 1976, and had a catalogue number of KG-001.  Issues from KG-003 (KG-002?) onwards came out on the Slate label. King George was run by the keyboard player with Black Slate at the time, 'Sir' George Brightly, who produced 'Mixed Up Man'; he appears to have got promoted from 'Sir' to 'King' at some point, which isn't a bad leap if you can make it. It issued singles in an TS-000 numerical series. Distributed By King George Records. Thanks to Robert Lyons For The Info.
