Dear Michael,
                      In response to your first post, you're correct in almost every detail. The album cover was essentially white with a monochrome collage of some broadside ballads. As to the spelling of Nic(k)'s name,in all subsequent references to the album I can find (I don't have an original copy either!) it is spelt correctly without the 'k'. The vinyl album was released in 1968 on the Broadside label (BRO 106) with, as you say, the tracks shared between The Halliard & Jon Raven, but again, as you state correctly, Jon did not sing with us. A modified version of the album entitled: 'The Halliard:Jon Raven/The Jolly Machine' was issued on CD in 1997 (Mike Raven MR 77). This link will provide you with a little more detail:

Is there any chance that you still have a copy of the TES review you wrote all those years ago? I have a small Halliard archive, but reviews, good or bad, are very rare items. It would make a valuable addition.
                      Nic & Julia do indeed now live in Devon, Dave is currently in Ireland & I'm in sunny East London. Are you aware that on the 28th May at the Queen Elizabeth Hall, on London's South Bank, there will be a concert entitled: 'In Search of Nic Jones'? Nic will be making an appearance, surrounded by a coterie of musician friends...should be a truly memorable & emotional evening.
                      Fascinating to read your posts,
                                                                            Very Best Wishes,
