Cover of QUESTION in 1977 - melody refrain Danielle
Cover of TRABAJANDO EN EL FERROCARRIL in 1977 - his Zjoske, Schone Meid sounds strikingly similar, although no one would doubt this is purely a case of coincidence
Cover of DARLIN' COMPANION in 1978 - vaguely but clearly echoing in the melody of Vlaanderen Boven; new versions in 1990 and in 2002 when it became the official celebration song for the 700th commemoration of the Guldensporenslag
Cover of SI TOUS LES GARS DU MONDE in 1983 - in Marc Didden's debut film Brussels By Night; similar refrain (Si tous les gars du monde voulaient se donner la main) and mood; rest of the lyrics and music all his own
