Independent label: Major Oak Records named after a famous old oak tree in Sherwood Forest. And based in Ockbrook, Derbyshire. The company issued at least two seven-inch records,  a Notts County FC supporters' song, 'The Magpie Song' by Reg Cooper and others (MO-1; 1973) and an eponymous EP by Focal Point (MO-2; 1973).  LPs and EPs were numbered in the same MO-0 series, to begin with at least; the highest number - of five! - that I have seen listed was MO-101, an LP by Tantalus, which came out in 1977.  MO-5, Stu Stevens's 'Command Performance' LP, came out in 1976, and I can't imagine that Major Oak issued nearly a hundred records in a years, so presumably MO-101 was the start of a new series.  There was also a Various Artists LP, 'Country Music Festival', featuring British Country artists such as Brian Golbey and the The Hillsiders.  Distributed By Major Oak Records.
