JS Records was a DIY label. And Another of those labels which is shrouded in mystery.  For a start off, there's no indication on the label as to what is the name of the company which made the record: I have called it 'JS' for the sake of identification, because that is what the first part of the prefix was.  As can be seen from the scan, JS EP-01 was an EP by a band called Reaction, which featured the tracks 'He Ain't Heavy He's My Brother' and 'Tomorrow Came Yesterday', as well as 'Runaround Girl' and 'Something Wild'.  It is undated, but 'He Ain't Heavy' was a hit in 1969, which pushes the Reaction version into the '70s at least.  A song called 'Runaround Girl' was put out by Richard Torrance in 1978; if the EP track is a version of it, that suggests a release date of late '70s or early '80s.  Googling reveals no other records with 'JS EP' prefixes, nor indeed 'JS S' or 'JS LP' ones; so, unless somebody connected with the band reads this, there we must leave it. Distributed By JS Records.
