Hello John
I can add a few to this list though not sure all of them are on the label under discussion also a few are I think later presses put out by or for Roy Smith and as such I don't know how legit they are, these are :-
Roy Smith Stay tonight with me/Oh pretty woman Delphi 1981
Roy Smith Sweet secrets/Faraway strangers Delphi 2011
and also included with these re-issues is I think
Roy Smith I got the fever/My marie Delphi 0015
back to the original numbering system
Wain Randell It don't pay/You could change your mind Delphi 0019
and then some confusion, as well as the 015 Obanion I think somebody must have liked the number because I have on the familiar black label
Ronnie Blackwood Nothings impossible/A funky night Delphi 0015
Hope this helps
Dazz
