Pierre Arvay used the pseudonym of David Prieston for the orchestrations and arrangements of tracks A8, B2 and B7.
He is not credited for orchestration and arrangements of tracks A2 and B1 although he created them. Indeed these titles come from the 45 RPM (7 inch) Le Chant du Monde n° EP‑45 3027 and Sidéral n° SW.M 3145, on which Pierre Arvay is credited.
