The label of Pluto Studios, now of Manchester but once of Stockport. Pluto was founded by Keith Hopkins and 'Lek' Leckenby, both previously members of Herman's Hermits. Recordings made at the studio usually ended up on other companies' labels - it was responsible for Brian & Michael's 'Matchstalk Men And Matchstalk Cats And Dogs' and The Clash's 'Bankrobber', at different ends of the popular music spectrum - but at least one EP, Pete Elliott's 'Pete Elliott Sings Skid Row Joe' (PS-001; 10/75) came out on its own label. As can be seen from the scan, which John Timmis was kind enough to provide, the EP doesn't have a label name on it as such, but the studio is mentioned on it. The PS-000 numerical series was used for custom recordings made by the studio, so there may be other PSes out there.
