Can anyone tell me who owned the Harp Pickwick Records Ireland?

Answer 1

Harp label, prefixed ‘HPE’, was a subsidiary of the London-based budget label, Pickwick. Harp Records was started by Pickwick Corporation, who opened up shop in Dublin in the early 1980's
Pickwick was bought out by Stoic Records and then Stoic went into liquidation. All the masters were then bought by Billy McBurney at Outlet, who issued countless compilations until told by the High Court in Belfast to stop, which led to the closing of Outlet Records.

Pickwick Records is an American record company, It also distributed recordings released on the Hallmark Records label in Britain.
