"À la folie ou pas du tout" ("Passionately or not at all") was the Belgian entry in the Eurovision Song Contest 1972, performed in French by Serge & Christine Ghisoland.
The song was performed sixteenth on the night, following Monaco's Peter McLane & Anne-Marie Godart with "Comme on s'aime" and preceding Luxembourg's Vicky Leandros with "Après toi". At the close of voting, it had received 55 points, placing 17th in a field of 18.
The song is a duet, in which both singers explain their philosophy on love - to "love passionately or not at all". They end by making the admission that "We love each other a bit much and we believe it".
It was succeeded as Belgian representative at the 1973 Contest by Nicole & Hugo performing "Baby, Baby".
