And as I understand matters, if a song is designated as copyright control, the royalties (for the record release & radio plays) goes into a central kitty that eventually gets doled out to impoverished British ex-recording artists (down on their luck).
So for all the US recorded UK released soul tracks that were MCPS copyright control, not one penny in royalties has ever found its way to any of those US recording artists.
MAY BE WRONG HERE but don't believe I am.
That's why US artists need to be signed to a decent label (Ace / Kent, etc) or be represented by Paul Mooney or his like over here.
