Bulmer aquired these masters in the first place I presume because
nobody else wanted them, I am not an apologist for Mr Bulmer, but
I don't think the demand is out there at the moment to make releases
in the normal way financially viable.
Bulmer's Music by Mail company has released, or will provide some of
them on request CDR'S I know, but still better than nothing.
I am not sure about the royalty situation, but I'm sure it will not
amount to much anyway.
