Part of the Plastic Fantastic family.  Blackbury seems to have run to just the two singles, both of which appeared in 1978. They were James Ashbey's 'Tomorrow Maybe' (PFU-5001), and 'Funky Christmas' by Spectrum (PFU-5002). Manufacture and distribution were by Pye, as they were for all the Plastic Fantastic labels in the '70s. Thanks to Robert Lyons For The Info.
