Hi Roger, apologys for the length of time it has taken for me to reply. Thank you for unearthing this moving poem. I have recently changed my email address so I have mailed my contact details onwards to yourself.
I recently came accoss another poem by Mark Vanner which I discovered in an anthology book. I have forwarded the details of this publication to your email address and hope that it will be of some help. I have also added the poem titled 'Street Lament(For H.S) ' to the exsisting library.
