I think the Rights Society has much to do with where the CD was to be sold.
Agreed, the CBS/Epic labels and such merely used a pressing plant in Austria, in fact it was there own DADC (Digital Audio Disc Corp.), hence DADC Austria in the CD matrix center ring.

Back to Rights Society MCPS/BIEM = UK, GEMA = Germany, STEMRA = Holland, SACEM, SGDL, SRDM = France. and so on.
