Anonymous Guest, if, by "Halliards' LP" you mean "The Irish in me", released by Saga, then all three of us: Dave, Nic & myself, sang. The Halliard produced three albums in total, all of which can still be purchased here There is a fourth album, shared with & released by the late Mike Raven, but not available from Nic's website. Dear Guest, if your LP was in mint condition, it would be worth something in excess of £50.00 in today's money.
                                  Happy listening,
                                                             Nigel Paterson (Mandolin, The Halliard).
