Hi Rob,
That must be a very interesting (and time consuming) project. In some way I envy you.
I am very much looking forward to read/hear the outcome.
Regarding the Michael Cox single, which you mention, Tony Meehan is credited on both sides of the label
"with Instrumental Accompaniment directed by Tony Meehan".
As the size of attached pictures is limited here you can view the record here:
