Pierre Arvay used the pseudonym of David Prieston for the orchestrations and arrangements of tracks A8 and B8.
He is not credited for orchestration and arrangements of tracks A1 and B1 although he created them. Indeed these titles come from the 45 RPM (7 inch) Sidéral n° SW.M 3145, on which Pierre Arvay is credited.
