The Eurovision Song Contest question was (I think), Palais des Congres, Paris, France, 22 April 1978, a Norweigan entry by Jahn Teigen, Mil Etter Mil, which recieved the infamous "Nul Points"!!

Referenced from "The Complete Eurovision Song Contest Companion"

Gambaccini, Rice, Rice, Brown (Pavilion 1998)

I am aware that knowing the answer to this question before borrowing my brothers reference book to confirm the details makes me a very sad person but we all have our crosses to bear9! :)
