Very first version of the first single by Cortex, reissued as 7 inch for the 1st time. “I remember that I and Alain Gandolfi wanted to put ‘Mary & Jeff’ on the A side, but the producer decided to set ‘L’Enfant Samba’ instead because he thought that the voice of Mireille would be more selling than my piano… 6 months after, at the beginning of 1976, ‘Mary & Jeff’ was a hit in a lot of Disco clubs and radios!” (Alain Mion).
