The venue and host of the national final are currently unknown. Five songs participated and the winner was chosen by a 10-member jury. It is not known whether a full ranking of the songs was released.
On the night of the final Leclerc performed second in the running order, following Finland and preceding Spain. Voting was by each national jury awarding 3, 2 and 1 points to their top three songs, and at the close of the voting "Ton nom" had failed to register any points, placing Belgium joint last with three other zero points entries from Austria, the Netherlands and Spain. This was the second consecutive year in which Belgium finished the evening at the foot of the scoreboard. The Belgian jury awarded its 3 points to Luxembourg.
1962 was the first contest in which any entry had failed to score, and although four countries shared the ignominy, Leclerc is usually awarded the dubious accolade of being the first ever Eurovision nul-pointer, due to "Ton nom" having been performed earliest of the four in the running order.
