I'll throw my 2 penny worth in
Paul is 100% correct.
When i was the promotion manager for BC Charisma in the 70,s we would regularly licence the royalties to Lux 208 for the B side .
In those days all deals were done directly with Ken Evans in the London office
I remember loads Atomic Rooster Clifford T Ward Genesis.
Moving on 10 years to Laser 558 it was just cash.
