Independent label: Beal Feirste being the Gaelic name for Belfast it seems a reasonable bet that the Beal Feirste label came from that city.  It seems to have issued at least just four singles, three of which were by Folk band The Freemen. The titles of all four suggest that the label's owners had Republican leanings. The Freemen's 'The Flight From Mountjoy' came out in 1973 with a catalogue number of PDF-001; The next three singles were numbered in an FM-000 series.
